ANP200

This was a replacement for an almost identical unit that I have had several years (about 10 I think). This new one functions just as the old one did and the only reason I have given it 4 stars instead of 5 is because the cover for the USB port is extremely flimsy and flatly refuses to stay in place. (See image of it not quite closed)Other than that this is a useful tool with good recording capabilities making it useful for overnight assessment of sleep apnoea (apnea US). It is not designed to be worn when exercising however and walking around with it on can cause the unit to become erratic. This is NOT a fault of the unit.Measuring the pulse rate against that displayed on an Omron M10-IT blood pressure monitor the BPM is normally the same and never more than 1 beat different over several tests.

Picks up results faster than small fingertip one I have but I’m bed bound so easier to find and use! That’s why I bought it.Oxygen reading always around where it should be but HEART RATE is way off mine normally between 94-114 depending? Hope this Helps !

USELESS piece of equipment if the small screws holding on the battery cover cannot be removedI’m a mechanical engineer and whilst one screw came out quite easily, the other was either seized or been put in cross threaded. Don’t expect a 30 minute battle with a set of watchmakers screwdrivers from opening the box.Of course - I could have got it open but not right out of the box

I thought it used Bluetooth but just a nightmare setting up software

Wry useful for the clinic - clear and easy to use
