Finger Pulse Oximeter, Fingertip Blood Oxygen Saturation with Pulse Monitor Rechargeable, Accurate Spo2 Reading for Home, Outdoor Sports，Green

After several days of use, this pulse oximeter has proven to be accurate, reliable, and very practical. It's lightweight, easy to use, and provides quick readings for both oxygen saturation and heart rate. The battery lasts a long time, and the display is clear even in low light.Perfect for daily use, whether at home or in clinical settings. Highly recommended if you're looking for something functional and durable.

It has been very useful to me, it is easy to use and small to take everywhere, it fits anywhere. It recharges easily with a USB cable, and its battery lasts, The screen was easy to read and understand and the readings were accurate.

Takes about 5-7 seconds to register the fingertip reading but works well and accurate. Large display for Elders and rechargeable. Sleek design

Works great! Easy to use. Quick and easy to read results. Charges quickly with usb-c (included) and can get many readings with each charge. Great value!

Works really well. Super easy to use. Love that it turns off as soon as you take your finger out. Easy to hold and store. Love that it charges.

This thing is a good deal. Screen is easy to read with the result numbers being bold & bright. Charges quickly (thru usb-c which is always appreciated) and lasts a solid amount of time/uses per charge cycle. The sensor accuracy seems fairly decent with it having a similar result compared to my smart watch. Sometimes it seems a bit off but if you reset it by closing it and opening again or put it on and let it stay on your finger for around 30secs-1minute it will correct itself. Build quality is decent, you should be careful not do drop it because the plastic seems a bit cheap but at this price for a rechargeable oximeter you can't complain *too* much. Lastly, it's obviously portable as the product remains true to it's picture. It's as small as a mini candy bar and can fit in almost any pocket or be attached via the mini lanyard they provide.I can't speak for the longevity of this product, since I've only owned It for around one month, but so far no issues. I bought this model because I wanted an oximeter that was rechargeable rather than replacable-battery operated (for obvious reasons) so as long as they put a decent quality lithium-ion within the unit it should last many years with zero issue. My only notes is that the manufacturer should consider using a more durable plastic for the colored housing, a redesigned grip on the back area as it's sometimes hard to open the device, and a durable matte coating on the screen to prevent scratches/dents/etc. If they do that then this device will be perfect for my needs.Overall would definitely recommend this to anybody that needs a simple/easy, stylish, functional oximeter for home + travel that also has the benefit of being rechargeable.

So far it works great.

This was great buy. It was easy to use and small to be carry everywhere. It's easy to recharge by USB and last for days in between charges. No need to worry about battery changes. The display was easy to read and understand and also the readings were accurate.
