Bests & Worsts Reviews from Amazon

Like pretty much everything about it except for one fatal flaw which overrides ALLthe rest and makes it TOTALLY useless after the first time the memory becomes full. I have chosen to forgo the benefits of using the app, since the permissions it requires in order to function presents a high hacking risk (to me). No problem; that's my choice. However, I now have a full memory, and it will not provide me ANY readings as long as the memory is full. OK, I'll clear the memory. HOWEVER...I CANNOT CLEAR THE MEMORY WITHOUT USING THEIR APP!!! Removing the battery does nothing. There is NO reset button. THAT MEANS THE DEVICE IS NOW TOTALLY USELESS $80 PAPERWEIGHT, AS IT WON'T EVEN GIVE ME A SINGLE READING. WHOEVER HEARD OF SUCH NONSENSE??? Have to download an app, with read/write access to my files, with a tiny number of downloads, from an unknown vendor in China, in order to get even single, unrecorded, non Bluetooth readings??? This is beyond unreasonable. One assumes using the app is optional for bare bones functioning, not mandatory. ARE YOU KIDDING??? MINUS 10 STARS. Furious!
