I love how you can Bluetooth it to your phone and it's on point and easy to use, it fits perfectly on your finger and it doesn't pinch or isn't to tight it's well made and easy to read

I like this item a lot , I recommend this item and seller

Hospital recommended that I get this. After I had open heart surgery, I was needing to monitor what my heart was doing. I would have given this five stars, except that you can't see it when you go for a walk in the daylight. This item is primarily for indoor use. I still have mine, but now I have a watch that does the same thing, will they watch face that I can see outside when I'm walking.

I purchased this meter because my other had quit, I was really disappointed with how inaccurate the new meter was, I returned the item and was refunded my money. The company had reached out to me to discuss the problem in at which time they sent me another meter to try and this one works well. I must say this company has some superior customer service and they do care about their product and the customer as well. I do recommend this product and thank you again!!!

This item truly work for me is small enough to be in your purse,at all times.

Good quality, well made and easy to use. Just load it with two AA batteries that are included and turn it on by pushing the button on the top. Has a large LED screen that lights up and is easy to read with big large letters. Put your finger inside until it stops beeping and is ready to read. Has an easy to understand manual that goes through all the functions Good price, highly recommend.

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.

One of the standout features of this device is its Bluetooth capability. It seamlessly connects to my smartphone, allowing me to easily track and analyze my data through a dedicated app. The app is user-friendly and provides detailed insights into my oxygen saturation levels and heart rate. This has been extremely helpful in identifying trends and making necessary adjustments to my lifestyle.
