This is an excellent Pulse Oximeter for a self monitoring system.
This is an excellent product for anyone who may have to monitor their blood oxygen levels. It has been a great companion for me after a major surgery that made it necessary to monitor myself several times a day. It is precise and easy to use. You can wear it around your neck if you have to constantly monitor yourself. 7 month and I haven't had any issues with the battery life. I haven't had any problems reading the numbers they are large enough to read. It is an excellent product for the money. It is muti functional.

Nice.
Easy to assemble, power on, use and read. Decent value. Concerns include that if the unit is too tight around your finger, it will cause inaccurate, overly high readings. Position your finger directly in the center of the oximeter.

Overall, it works well and I would recommend it.

Track Oxygen Levels
Works well, easy to use, good price but the numbers are small and hard to read.

Great device to have in my first aid kit
I had to replace an oximeter I got since the pandemic onset, so I saw the one sold by HealthTree and decided to order it. Its size and light weight make it easy to carry this device with you, whether you travel away from home frequently or seldomly. In my case, it’s important to have a reliable device to keep track of these two metrics. I like it’s very easy to operate and the auto shut-off feature becomes handy to ensure batteries last long enough. I contemplate this is a must-have for every first aid kit at home.

Reads Oxygen levels well..
This Oximeter worked great. It arrived on time, no trouble using it on different finger sizes and has good battery life. I’d say it’s good value for the price. No photo sorry.

Very good
A very good product. It is small, lightweight, and super easy to use: you simply place it on your finger, and within seconds, it gives you a reading. The display is clear and is easy to read, even in low-light conditions. I have used it several times, and the measurements seem quite accurate. It is ideal to have at home, especially for older adults or for general health monitoring. The battery lasts a good while, and I haven't had any issues so far. I highly recommend it for its quality and great price.
