Not so good so far.

Out of box the pm will not zero.

Some features on app like rename device will not work either.

Showing 49% battery. Not sure if it was to come fully charged.

Previous pm worked fine. I’ll let it charge over night and try again soon n morning.

better blind than 4iiii's ,

Worst app ever

Thankfully did not have to use the app in over a year. This app has not got any better, provides zero feedback, and just leaves you incredibly frustrated. Tha app is not useful at all which is a shame for such expensive hardware. This is really a zero star rating.
