SAYTAY Small USB Fan with Real Time Clock and Temperature Display, Personal Portable USB LED Clock Fan, USB Funny Toy Gadgets Gifts for Men Women Office Home (RGB)

I bought one that showed a clock face at a gift shop on a recent trip to Canada, and it got some attention at work. Of course it also works as a decent ‘air flow-er’, making the still air in my work space move when it gets stuffy. I had looked up the device on Amazon and had noticed this programmable one and had thought of getting it a few times. The reason I have been holding off is the negative reviews about it broke after some use (hope that does not happen) and it is not detected by the PC and so it is not programmable.It came in almost the same package as the clock fan and the fan looks almost identical. The software is on a tiny CD and the files are small too. I plugged the fan to my PC’s USB port and it displayed the messages it came with. At first I was worried as I did not see any message on my PC saying it detected the device, but the software had an icon that supposedly implied the device was detected. I typed in a message and tried to upload it and it did not do it. I scanned the manual for answer and realized the fan should be off. I tried again with it off and a green light on the blade began flashing - and after it completed I turned on the fan and it worked as advertised. I found out how to change color and it was simple enough. It is also possible to edit the pixels, with each column of pixels can only be in one color. The fan gives a low humming sound but it is no big deal. I am happy with the purchase now let’s hope it lasts for at least a couple years.3/26/19 - I bought a second one . Summer is coming and I want two to put side-by-side. Rather than flashing bright and sometimes embarrassing text, I just have them flash dots rotating and cycle the dot color. I have them both hanging off from a monitor's USB ports.

This item worked perfectly. It was very cool. And then it quit working after about four weeks. The return button is no longer visible so I guess I'm just out of luck. If the seller contacted me I would more than willing to send it back and try for another one. I loved everything about the fan.Update: I received an email stating a new fan is on the way with no additional charge to me. I will upgrade to four stars if I receive the fan. If it lasts longer than four weeks I will update to five stars.Update: I never received a replacement fan as promised. Back down to 1 star! I would give zero if I could!

The fan has reasonable build quality; no complaints. It is good-looking; the shiny parts are shiny and the USB connector is solid. It isn't noisy at all and has only the slightest vibration. The display on the fan is bright and colorful. I had a heck of a time installing the software. Turns out another reviewer resolved the problem by removing the chinese characters from the file names and folder names. Installed perfectly after I did that. Thank you. I use Windows 11.

Software only works if it's copied to to computer. Works with Windows 11

I saw a co-worker with the older, monochrome version of this LED fan, and decided on a whim to buy one for myself. When I realized that there was this RGB (variable color via Red Green Blue) version, I bought it instead.The fan seems to be of decent quality. The USB connector and metal goose-neck seem solid. The fan body appears to be metal, but is probably just metalized plastic. The fan blades are flexible frosted-transparent plastic, and one of the two blades has an embedded flexible circuit board inside, having a row of tiny LEDs. When the fan rotates and the digital circuitry inside the fan pulses the LEDs in the correct sequence and at the appropriate rate, it paints an image that our eyes' persistence of vision allows.The fan comes with a tiny four page user's manual, and a mini-CD ROM disk. On the disk is a single folder, and you need to copy that folder to your computer hard drive. The file contains a primary EXE (executable) Windows program file and some support files. You run the EXE file to program the fan's displays, but there is nothing that needs to be 'installed' in the way that most Windows programs need to be. There is no support on the CD-ROM for Apple computers....Windows only! However, nothing stipulates which version, or versions, of Windows will work with the included files. Because this is from some unknown Chinese manufacturer, and I did not trust their software, I ran mine on an old Windows XP computer that I keep around just for programming such things as this that I get from China. Anything 'amiss' with the software and my main computers are still protected. So I know this software will work at least as far back as XP, and probably up through at least Windows 7, maybe even 10.When run, the EXE program presents a single screen for programming the fan. It has three regions:- Message area- Keyboard and symbols area- Simulation areaIn the MESSAGE area are eight text fields where you can type in eight text messages to be displayed on the fan. According to the user's manual, you can actually program as many as 20 messages, but it was not immediately apparent to me how to get to the remaining 12 text fields. According to the user's manual each message can be up to 20 characters long, including spaces, but in reality it is limited to 18 characters per message. Each message can be comprised of upper and lower case alphabetic characters, numbers 0 through 9 and punctuation, plus a set of graphics characters and a set of 'emoticons' such as smiley and frowney faces and hearts. After you enter the text of the message(s), you have the option of selecting three parameters for each of the messages. The parameters are (I paraphrase their titles here):- Opening- Display- ClosingOPENING dictates how the message will appear, and you can choose from a short list that includes "Scroll from left to right", "Scroll from right to left", "Scroll from top to bottom", "Scroll from bottom to top", and "Suddenly appear without any scrolling". CLOSING has the same options as OPENING: DISPLAY dictates what the message does in between the OPENING and the CLOSING, and the choices are things like "Rotate clockwise", "Rotate counter-clockwise", "Flash 3 times", "Display steadily without any effects".Besides the above, each message has the option for actual image editing. Clicking a special icon next to each message's text field will open a new window that shows an enlarged bitmap of the text as currently specified by the main editing screen. The pixels of the characters and graphics of the message are all editable, using a pen tool and an erase tool to set and clear individual pixels of the message image. So you could, for example, modify the shape of an alphanumeric character or graphic, or draw some artwork not available via the computer keyboard. There is also a Marquee tool that is not mentioned in the user's manual, and which I could not find a reason for, nor what it was supposed to do. Below the dot matrix of the message, described above, is another smaller dot matrix that allows you to control color. There are about eight colors defined, and each color is assigned to a row of this dot matrix. Clicking cells in this matrix will assign the color from its row to the intersecting column of the message matrix above. You can not change the colors by rows in the message, only by vertical columns in the message matrix. On other words, you can specify that each pixel-wide vertical slice of the displayed message has a color of your choice, but you cannot similarly specify the colors for each pixel-wide horizontal slice of the displayed message.I had problems with this part, the detailed pixel editing of the messages. First, the dot matrix cannot be scrolled within its special window, and while the window can be stretched until it fills your computer screen, at least on my computer this was still not wide enough to allow editing the entire width of a message if that message was using the full possible 18 character message length; some portion of longer messages will not be editable. I consider this to be a bug. On certain computer and monitor combinations, this might not be a problem. Another issue was that while the pen tool allows selecting individual pixels to be ON, the eraser tool seems to work on small blocks of pixels, not on individual pixels. It is probably this way to allow quick erasure of larger areas of the dot matrix, but it makes for a tedious chore to set and clear individual pixels.At any time during message entry, parameter selection and optional pixel editing, you can click the Preview button. The SIMULATION area will show an approximation of what the fan's images/messages will look like, although in many ways what appears here is rather inaccurate. Still, it gives a decent confirmation that you will get what you expect when the program is downloaded to the actual fan. You can click a Stop button to cancel the simulation at any time.When your program is ready, you need to make sure that the fan is plugged into the computer's USB port, and then you click the DOWNLOAD button, The screen shows a progress bar graph while one of the LEDs on the fan flashes. This took perhaps 20-30 seconds for 5 messages in my tests, and will probably take longer if you have more messages. At the conclusion of the download, the program returns to normal.You can save your program to your computer hard drive. You should be able to store any number of different programs.There seems to be no method for UPLOADING a program from a fan to the programming software on the computer.A single button on the body of the fan turns the fan on and off. When on, the fan will spin and any message(s) programmed will be displayed in order, one after the other. When the last programmed message has been displayed, the cycle repeats from the first message. Pressing the button again stops the fan and the display.I found the displayed messages to be bright and clear, and quite stable in appearance. There is no brightness control.The fan is reasonably quiet, just a whisper. It does not move much air, but of it is within a foot or so from your face, you will feel it. It is really a visual novelty, and is not a serious fan for real cooling. The motor is low powered, and the fan does not really spin all that fast. Couple this with the soft flexible fan blades, and it is very unlikely that the fan would do any damage to anything that might contact it. I stuck fingers into the fan several times, and it just stalled the fan and there was no pain to my finger. The instructions state that after 3 hours or so of operation, you should shut the fan off for a while to prolong its life. This is confirmation that the product is not really a serious fan for cooling.The fan blades are not perfectly balanced, so there is some low level vibration. Much of this is taken up by the gooseneck. If the gooseneck contacts a desktop or other object, you might get some objectionable noise as the vibrating gooseneck rattles against the surface of the object. I noticed that the fan blades were somewhat deformed from long contact with the packaging, and initially there was a lot more vibration. After a couple hours out of the packaging, it seemed that the fan blades resumed their proper shape and balance, and the vibrations lessened.One other thing. The packaging and user's manual state that this fan uses "micro wave". Presumably this is for getting the program data from the computer to the digital circuitry in the head of the fan that controls the LEDs. Not sure what they mean by "micro wave", but I am not too sure that they literally mean microwaves are carrying the digital data. Presumably some sort of wireless data transfer is used, and it is unimportant which kind. Hardly seems like a selling point that needs to be mentioned as if it were a feature.So, a cute novelty product that basically works well, but has some issues with less than fully developed programming software, minimal instructions, and an apparent build quality that will not likely survive heavy or continuous use.

How to explain it properly!!!!I have never even though about this till I got it. I mainly use it for my son to watch my messages but he is in love with it. We both enjoy this soo much and everyone that see it has the same feeling. It's programing is extensive and there are a lot of options that you can do.I was afraid this would not last long (for the price) and left it on for two weeks straight without a break. I was amazed to find out that it was working the entire time and wasn't even hot at the end of the two weeks. (Location) I'm from Florida and here is always hot. So believe me is impressive that this thing worked as it did. I will definitely recommend this to anyone that would like to give a nice surprise to someone else. Or even to play by themselves.This is a quality product and a great toy to show others and brag.

I had to install it on my Windows 11 pc in Windows 95 compatibility mode. I found a newer version of software online but had to use the old to transfer the file to the fan. Works great though.
