This piece is just as awesome as the Red Cat 51 itself. The only negative was the fact I did not receive the instructions that should have come with it. So having a nice new piece of gear I was very cautious about taking anything apart. But a call to OPT's 800 number took care of all my problems! Diana was able to ask a few pertinent questions compare a couple of photos and sent me the instructions I needed. Problem resolved. No waiting on hold just a few text messages in a few minutes was all it took. Awesome customer service / Technical support and a fine piece of WO equipment too.
