This works and its easy to use.
I was surprised, this actually works well and is easy to use, and pretty darn accurate. I'd recommend it. I also recommend you bring it to your dr's office (as it states in the instructions) and get it calibrated to match what your Dr's much better equipment says - or just take note of what the difference in the readings are- and apply that in future readings from this little machine. I have tried other brands of these but this one seems to work pretty well, have owned mine now about a month. Only thing - you need a USB port to charge this from - like on the side of your lap top or whatever, but it only needs to be charged 1 time - and then it lasts about 200 times per the literature before needing a recharge. It was easy for old Fumble Fingers Thompson to put on also.  .
