I don't normally do reviews - but I thought this needed to be said. I bought 2 RPG12BTV2 from Amazon. Both arrived but one was wrong model - Amazon gave me a refund. This was not Rockvilles issue. The second one did not work from the beginning. This is where the issues begin - since Amazon would not refund a second time I went to the Manufacturer- this initially was a little painfull. Phone calls - waiting for tech support to call back several days - I was getting a little steamed. Finally I got a tech and got an RMA. I happened to be working very near the RMA center so I went to bring the RPG12BTV2 back directly. When I got in the building I was introduced to Michael- he took my RMA and got it expedited for me. They had it fixed later that day and and I picked it up the next day. Michael did a great job for me and now time will tell when I put this to work. I know other people have had some horrible experiences mine wasn't too horrible. But they could do a better job up front with customer service - buy my in person experience was great.
