I really like this system. The booster is a great idea and I haven't had any connection issues yet. I have a few issues, one of which is that I don't want to remove the lock nut on the back of the gauges so I have enough room to check air pressure with a mechanical gauge or inflate the tires with air. I think flow sensors would be a better idea. Another problem is that the pressure differential between the mechanical gauge and the pressure gauge is about five pounds. I run my RV tires at 105 and the meter reads 110. Tireminder has a reason for this and states that there is a 5% difference, but in my opinion they should be accurate. I think I've put about 2000 miles on four of these and they've all worked well.
