Customers say
Customers find the pulse oximeter easy to understand and use, and consider it good value for money. The device measures oxygen levels effectively, with quick results showing within a few seconds, though some find the numbers hard to read. The functionality and accuracy receive mixed feedback – while some say it works excellently and provides reasonably accurate readings, others report it stops working properly and gives inconsistent results. The device’s durability is also mixed, with some describing it as well-made while others find it flimsy, and the battery life varies between those that come with two AAA batteries and those that arrive without them.

Works great
Works as intended, does not work for my 5 year old whoâs finger is smaller. But works great for the rest of the family and we love it for a peace of mind when sick.

Out $11.
I first bought this in 2020 during the height of Covid when there were so many scary stories about dropping oxygen levels. I wanted to check! This was inexpensive and came quickly. I now have a health issue where my doctor wants me to check pulse and oxygen daily so I was glad I had this. Itâs the same brand the doctor uses. After four years it just began having issues. It turns on when I insert my finger, but then after a few seconds it just goes blank and displays no data. Since it still had the original batteries I decided to replace them. But even with new batteries it still just shuts off without displaying data after a few seconds. Still, it worked perfectly for four years, and the price is right, so I just decided to order it again.EDIT: new one arrived and itâs defective. Gives crazy and inaccurate readings like saying my O2 level is 77 to 80%. Clearly wrong since I feel perfectly fine and my Apple Watch says my O2 level is 97%. I canât even return it since return details say it must be placed in itâs original packing materials, which I no longer have. Oh well. At least itâs cheap but I guess Iâm out $11. I was happy with my first one for four years but if I buy another it wonât be this brand.
