Really easy to use once you can get the batteries in. Nice to have a piece of medical equipment to use at home that is comparable to the ones at the Drs. office to make sure you're in optimum health.
Very handy tool especially for one with asthma and difficulty breathing to know what's going on and if they need oxygen or to go get help. This one doesn't come with any type of holder but it works and happy to have it.
The design of this device is nice. It’s attractive and has a bright, easy to read display. However, half the time it won’t give a reading at all and if it does it’s very inaccurate. I’ve got another one that works and this device reads 84% while the old one I own reads 98%. Very unhappy.
The first order would click off for some reason. When I contacted company. They were very nice and sent replacement and a free better one and a mask. Which was wonderful. The replace ment ones are ok for the price. Haven't used them long enough to see how long they will last. If a person has trouble with them the company is very good about solving the problem. Try them and see for yourself.
Small, one button, easy to use diagnostic tool for people with asthma & COPD. LED screen is very easy to read. Takes 2 AAA batteries. Very convenient and economical. Highly recommend. Reads blood oxygen saturation levels and heart beat rates in real time. Color numerals for pulse and O2 sats.
