Works only on batteries, doesn't support rechargeable batteries. Plus and minus are soldered symmetrically for two batteries, although the connection is asymmetrical. Simply put: one plus with a spring. Made with the left foot. Otherwise, everything works, but I can't vouch for the accuracy. The stated price is ten times less than in pharmacies, so such a toy can be purchased.

I waited a month for the package. I didn't use the pulse oximeter because it needs batteries. It looks like good quality.. Adding to the review: I inserted the batteries, I'm using the device, it works perfectly. I am very happy and grateful that I can instantly find out what my pulse is and what my blood oxygen level is. Thank you 🙏💕!

The product took exactly a month to arrive, which corresponds to the stated period. Well packaged. The quality of the product is unsatisfactory: with new batteries it turns on empty, does not work as it should on the finger. Does not turn on, does not show anything. Money down the drain. I do not recommend.

I inserted new batteries, but the pulse oximeter still didn't turn on. I bought this little device as a trial to then purchase more for the soldiers in the SVO, but now it will just lie around...

The instruction is not complete, it shows oxygen, and pulse too. But when you press the second time, the numbers are unclear about what. The instruction doesn't say. There is a number with the letter L?

It works, but it's unclear how to turn it off. After some time (3-5 min) it turns off by itself, which is a lot. The battery will run out quickly.

A good, convenient heart rate monitor and determines the oxygen in the body. You can quickly check your pulse if you are worried about your heartbeat.

The pulse oximeter is normal. It shows heart rate and blood oxygen level. But it doesn't always show quickly for some reason.

To my great regret, the pulse oximeter shows incorrect data, it's a pity, I had such hopes for it

Complete crap....doesn't work....just blinks and shows nothing. Ordered two...both are garbage. Do not recommend

After a week of use, it started not turning off. We remove the batteries after use. Maybe it will come to its senses.

It works, but there is no way to verify or calibrate it, so you can only trust it, especially the "oxygen".

The item arrived in non-working condition, I request a refund, or to send a working pulse oximeter.

Haven't used it yet, need to put the batteries in first. Everything is fine, it works well

This is not a real product, it does not work at all. Most likely it is a toy device

The device doesn't work, the lid is broken... I demand a replacement of the product or a refund of money

Thank you. I inserted the battery. The heart rate monitor works properly. Very satisfied.

Well packed. Intact. Only the measurements are questionable. But for such a price ...

The pulse oximeter works great, thank you It stopped working after a week

It works, but how it's supposed to be is unknown. 95 by 62. Is this normal or not.

Batteries are not included, I inserted my own. The device works correctly.

It doesn't work. I put the batteries in, but the device won't turn on. It's a shame.

Received today, don't have a battery yet, haven't tried it, stars in advance.

Having inserted the batteries, I checked the pulse oximeter, it works, thank you

The packaging is intact. I need to buy batteries and try them out...

Thank you. It works. Regarding accuracy, the measurements are for the entire settlement.

Batteries are not included... so I haven't tried it yet

The packaging is good but haven't tried it yet need batteries thank you

Haven't checked yet. Checked everything, it's all normal, thank you very much.

The pulse oximeter is faulty, does not show pulse values.

Honestly, I can't figure it out at all, but everything is intact. Thank you

Doesn't work, shows nothing, although the lights are on

A pulsar arrived without one side of the contacts. What to do!?

Tried it out, a good little device, shows saturation

Thank you, having received it, I haven't quite figured out what's what!
