I bought mine on sale directly from them. It arrived and wouldn't pick up suppressed shots or some shots from high or low on the radar, they took it back and replaced the microphone and hasn't failed to pick up a shot since. I'd never go back to a traditional chrono, worth every penny.
I also have four shooters in my home including a preteen girl who's got her first PRS match next weekend so a magnetospeed speed just doesn't make sense for my application. I might test three or four rifles with many different loads on a test day if I changing bullets or similar so swapping it all over and the tangle of wires to drag back and forth accross the other items on the bench for me was a deal breaker. If ever Bluetooth made sense for a shooting item it's for the magnetospeed.
