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

It works perfectly
A very good oximeter, easy to use, and with quick and accurate readings.I love that it’s rechargeable; I don’t have to worry about changing batteries.The green design is attractive and looks durable.Ideal for keeping at home or taking with you during outdoor activities.

Inaccurate Readings and Poor Display Quality
I bought this pulse oximeter hoping for a reliable way to track my oxygen levels, but it has been nothing but disappointing. The readings are inconsistent and often don’t match up with medical-grade devices, even when I’m sitting still. At times, it showed numbers that were clearly wrong, which makes it impossible to trust for home monitoring. The display is supposed to be bright and easy to read, but in natural light it’s extremely dim and hard to see. I also noticed it tends to glitch, sometimes freezing mid-test or refusing to start unless it’s plugged in. This defeats the purpose of having a rechargeable portable device. For something marketed as accurate and dependable, it falls far short.The heart rate readings were also unreliable, sometimes showing dramatically different results just seconds apart. I tried multiple times under different conditions, but the numbers still didn’t make sense. The overall build feels cheap, and it doesn’t seem like it will last long with regular use. I was skeptical about the low price compared to the models sold at pharmacies, and unfortunately, my instincts were right. This might be fine as a novelty or for casual curiosity, but it’s not suitable for serious health tracking. I’ll be replacing it with a more dependable unit from a trusted brand.

It’s green!
It is green! Comes with a USB-C cord and a lanyard. It was not charged when it came but I plugged it in and it works while charging. Easy to read digital display.

Supringly good value
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.

Buen tamaño y buena precisión

El Oxímetro presenta muy baja presición para detección de Oxigeno capilar. El pulso se aproxima; pero la SO2 no corresponde a los vlores reales, comparado con oximetros de otra calidad. No acosejo su compra y menmos su uso para monitoreo específico.
