I recently bought the Brake Buddy vantage select and I've used it the last 4 times I've moved (full timer). The first three moves it seemed to work fine. The last move of about 200 miles I struggled getting the remote to indicate braking (red light). I could change sensitivity. however, the sensitivity changes seemed to be flakey meaning I had to push the buttons two or three times. At all times I was using the 12VDC adapter. The wife was getting irratated with the hard braking and I had to convince her it was an important test

.
Once I unplugged the 12 Volt DC adapter and used the internal battery only the remote seemed to start working properly, indicating braking and adjusting sensitivity as selected. This seems to be related to an RF issue between the Brake Buddy and the remote.
Is there some trick to placement of the remote, or is there a trick when using the 12VDC adapter??
