69 mechanical mod clone 

Thanks for making a review about the unit instead of 25 minutes of face closeups like so many reviewers do.

u just gotta keep messing with the pins make sure they get contact. i had the same problem but i figured it out.

I bought one of these and can not get it to work. I but battery in tightened up and put a pro tank 2 on and nothing. I sent it back got another one and it won't work. I push button and nothing happens. Any ideas? I can't believe I got two broken ones.
