Bluetooth Pulse Oximeter Fingertip-HOLFENRY Oximeter Blood Oxygen Saturation Monitor spo2 Pulse Oximeter Finger, For Heart Rate Sat% Oxygen Saturation PI

Very reliable tool for checking heart rate and o2 stat. This meter correlates with Dr offices meters. Sometimes they even uses mine at times. Batteries last long time.

Works excellent and easy to read. Fast too!

Can barely see red lights and two months later it broke Update: the seller saw that my product was defective and refunded my money without my having even asked. I hate to leave negative reviews and hope this was just a defective one I received. I really appreciate the seller caring about my experience. Very Trustworthy & Upstanding Thank You

This Pulse Oximeter is very reliable which is important given I am on Oxygen and use the Oxygen daily and need to have a well-made fingertip Oximeter that I can rely on. I would purchase this brand and product again if needed, but it lasts and is well made. I have had it a good while and it works well. It has given me no problems only have had to change the batteries a few times. I have a home nurse that visits me weekly, and she uses her oximeter on me when she comes, but I have tried mine after she takes my levels with Her's and doing this tells me that my oximeter is accurate for it gives me the same reading as hers does.

Yep this works bc my heart was racing and it caught how fast my heartbeat was going and just confirms my anxiety yay lol but it was really easy to set up you just put in the two batteries it comes with and push the power button and put your index finger in it like the doctors office and it reads the heart beats per minute and the top number is like oxygen percentage. It’s easy to read, accurate, and quality it good- it feels good on the finger too my kid likes it too lol

Works

The idea of having your phone remember your O2 readings is great. The pulse oximeter is barely usable but the included app is pretty much useless. (The app appears to be 'new' and will probably be upgraded as kinks get worked out.) The display is LED (not LCD). It's dim and very hard to read indoors, impossible to read outdoors. The display can not be rotated for easier reading. The only readable position is if you were 'giving the finger' to someone. The first 'reading' takes almost 15 seconds and it takes about another 15 seconds before the readings settle down without jumping all over. The button on the top alternates the bottom half of the display between Pulse and PI (Perfusion Index). The SpO2% display will flash if it is under 94% On to the Bluetooth: It is an 'open' Bluetooth connection, meaning it is always on whenever the oximeter is on. It does not need to be directly 'paired' with the phone app. Instead, when the app is running, it is constantly searching for the device(s). When the app finds a device, it starts recording the data. When the oximeter is removed from the finger, the app restarts 'searching' for the device again. This constant 'searching' can easily drain the battery of the phone, particularly if readings are taken sporadically. The app will continue to run & search in the background even if you close it. However, it will NOT record any data unless the app is 'actively' open. The app can NOT be stopped except by going into the phone's app settings, finding the app, and doing a Force Close! As for the app's graphing capabilities, data samples are taken & plotted every 30 seconds. In graph mode, only the Sp02% and PR are displayed, but independent of each other. Swiping right/left of one graph will not move the other graph accordingly. The app can display a 'table' of results but if accessibility features for larger fonts are used they will not display correctly (the 'time' cannot be read because the 'date' fills the entire display field). Overall, the app is mostly a waste of time. However, it will display the current reading(s) in a very readable manner, making up for the poor display of the oximeter itself. Over time, the app designers will probably improve the app. The price was very reasonable. Since it is considered a 'sport' device and not a 'medical' device, the limitations can be expected. As a portable device to measure/monitor the PR and/or SpO2%, it does a fairly decent job.

I purchased this as a replacement for another Bluetooth monitor I lost somewhere. I have AFib, and quick periodic monitoring of my heart rate is helpful. Cellphone apps where one holds a finger over the camera were simply not accurate. This one combines old-fashioned technology with an app that measures and then tracks the data in the iPhone health app.
