A rather funny gadget - when we put it on a banana, it turns out that the banana has a heart and a pulse; moreover - even an oxygen saturation level of 98% - it must be a very healthy banana. It works with the phone correctly; it displays time and text notifications correctly. As for the sensor - it's worse (it dims like AI when it doesn't know the answer). Generally, it shows values close to those of a healthy person (but I doubt it actually does any measurement). In general, we buy a pedometer with a watch and a fun gadget when it comes to measuring vital parameters. I’ll try it with a tomato next - as the photos show - I have a very lively tomato. This watch is such a good joke - I highly recommend it for a laugh...
I am impressed. It even measures glucose levels accurately: watch 90, finger prick glucose meter 89, wow! It also measures cholesterol and has many other functions😀👍
