I dont even own a EI Commander yet and I can tell you Bills customer service is A1! I called him with a PMag question and he was a great help. I will be installing a EI Commander in the near future.

This is not only a great product but the best customer service I've ever gotten. This system found problems with my Pmags instantly. I would never install Pmags without the EI Commander.
