WellueBluetooth Pulse Oximeter Fingertip, Blood Oxygen Saturation Monitor with Built-in Memory, OLED Screen, Batteries, Free APP, Carry Bag & Lanyard

NO, I do not work for them or know who they are. I AM thankful they at least sell through Amazon. Not sure what their beef is with the US, but you can NOT buy directly from their website (which I think is total crap not allowing from US to purchase directly from them!). Aside from whatever THAT is all about, their products are VERY GOOD QUALITY, EASY TO USE, LAST LONG-CHARGE WISE, and GENERATE GREAT DATA ELECTRONICALLY you can send/print to give to your providers. or just to keep track of yourself. I have this same pulse ox-it is VERY accurate, but got this for my parents to use. It uses bluetooth technology, but does NOT store the data on the pulse ox like their more expensive O2 ring does ($165-worth the price if you need it overnight for respiratory or neuromuscular weakness diagnoses). You have to have the app opened on your phone for it to link and then it will immediately read the data from the pulse ox and will save it on your phone in the app. if you don’t have the app pulled up and have it on your finger- it works fine, but you won't have any of that data until you open the app.They have recently updated their app and it is MUCH easier to switch from device to device now (was a problem in the past). Their white one also works, but like this one-have to have app opened-doesn't store data (I use that one for my patients).Their BP cuff is great for my arm, but not likely to fit around large bulky arms-not sure if they have a larger size for that, but it's definitely a small-medium size and works really well and very accurate-nice being tubeless and wireless!!The scale uses a different app, but works really well for weight loss/management needs with tracking body fat, BMI, lean muscle and fat mass, water, etc. like the Tonida scales, except lighter and for home use. I'd say it's pretty accurate unfortunately! lol I have my work cut out for me for sure! but it connects easily to the phone as well.All of that can be purchased through Amazon I believe.So overall-ALL the WELLUE products are ACCURATE, PRECISE, EASY TO USE, EASY TO CONNECT, EASY TO SHARE DATA WITH MEDICAL PROVIDER, and can be used on multiple people if wanting to use for work purposes or a clinic use.For those who need an inexpensive BiPAP and can't get insurance to hurry up and pay for one, they have an affordable one you could just purchase outright. I have no idea if it is any good, but considering the rest of their products are top notch quality medical supplies for lay or medical people, I'd think that would be as well.

Works great. Consistent reading, large display for easy reading, beep alerts, automatically turns on and off to save battery.Not suitable for kids though. Fits only big fingers.

The Oximeter provides an accurate and consistent result. The waveform also is very infomative.

I have had about a year and had meant to write a detailed review earlier. Overall, I think this is a good purchase when regularly on sale at the $20 price point BUT is a big rip-off at the random $40-$50 price.I find the electronics comparable to other brands of products, with the accuracy generally better and the ability to read with adverse conditions (walking, cold extremities) much better. The electronic package is amazingly reliable considering the number of times it has been dropped/flung.The product housing is made of VERY CHEAP feeling plastic that will easily slip off the finger or be flung great distances with a sudden arm movement. This results in the device going one way and the batteries in several other ways. The CHEAP almost non-existent battery latch only barely worked for the first fall, I have had to tape battery cover on since then. Higher quality plastic over all with silicone finger insert area would have added minimal cost and still give an over 500% profit margin at the $20 price.My main reason for choosing this product was the app and overnight/long walk monitor function. I have found these functions to turn into more of a novelty and not used very often due to these issues. The App has provided valuable insight into sleep issues w/o O2 and several other sleep related issues that are not apparent with just wearing a device and checking when I roll over. I don't have any issues with the app operation or UI providing I keep my cell phone on charger near the bed and tape the Pulse Oximeter to my hand, so it doesn't come off or quit working.Many have commented about very short battery life. I use rechargeable batteries so that is less of an issue. Batteries last about 20 hours when monitoring with the app and several days when just wearing and checking periodically. Battery life could be greatly extended if the pulse oximeter included an option for turning off blue tooth.Due to the issues, I have discussed here; I generally use the Wellue Bluetooth Pulse Oximeter for random checks such as walk monitoring during the day and my other brand to wear or have nearby to monitor during my sleep.
