Got mine in today!
The size/form factor, as well as the ease of menu operation alone make this thing so much better than the LabRadar.
Did about a total of 40 shots with two separate suppressed rifles and it picked up on every single shot.
A slight word of warning however. If you're buying one get it home, charge it up, sync it with your phone and download the latest software before taking it out. I was actually about the middle of a group with one of the rifles when I took a break to let the rifle cool down. At that point the unit decided it was going to update the software and there was nothing I could do to stop it. It's saved the data from my first few shots as its own session. Didn't really lose any data but I had to go back and combine everything manually later.
Overall very impressed
