Has saved me countless times
This is one product I would buy again and again and again. Many times this has saved me my oxygen and pulse drop severely low multiple times a night the alarm on this wakes me up so I can raise my oxygen or pulse depending on the culprit at the time. The recording history is a plus. There is only one downside the app that you download displays the incorrect pulse so the alarm in the app has to be turned off for that since it reads about 200bpm which other app reviews have noted as well. If you’re just using the alarms on the device itself then you’ll be golden as the device itself everything works perfect. The only two things I’d suggest for a v2 of this would be the app fixed and the cord being a little longer since I often switch sides I lay on in my sleep

18 hour battery life?…. Ehhhhh… not so much…..
“After fully charged, the pulse ox can be used continuously for 18 hours” is their own description… After having this machine and using it fairly regularly for a few months, I can tell you I have NEVER gotten more than 8.5 hours on a full charge. Trying to monitor O2 sat. overnight with a CPAP machine, this item is dead in very short order. Sadly, the window for returns has expired, or this would be going back. Documentation is fairly flimsy and not very helpful. On the plus side, he machine seems to be fairly well made and accurate, so, there ya go, some good , some bad….edit on 08/18/2023 – I bumped up the review one star because of the OUTSTANDING customer service provided by Holfenry. The device and battery life is what it is, but they went above and beyond to make it better. Great company.

Lasted 3 day use.
This is a good device. It comes with a charger base, mine stopped working after the first night so im knocking 1 star off. Its still a good working device even with out the charger base, I just have to plug the usb-c directly into the device to charge, no big deal.Edit after a few days use. Well as mentioned the base charger stopped working after the first nights use. No big deal i could still charge it directly. Now after using it maybe 3-4 nights the actual device just stop working. It powers up, display comes on but it wont go any further. Ive tried to trouble shoot it every way possible. Its to bad because I had high hopes for it, it look good at first.

A good device for home oxygen monitoring
When my father’s health was failing, this pulse oximeter was an incredible device for monitoring him at home. Having continuous oxygen and heart rate monitoring made us feel almost like we had a hospital monitor at home. It’s excellent, and the best part is that the battery charges and lasts all night.
