Great ty

Easy transaction

Good pricing and fast shipping, good place to do your boat shopping.

I mistakingly ordered two of the product. someone from customer service contacted me to verify it I actually wanted two. So we cancelled the extra order. Most companies would not go that step in customer service, much appreciated. The product arrived really fast and was exactly what I ordered and worked perfectly.

Easy transaction

Thank for the prompt service.

Waiting on RMA for wrong color ordered

Love it, 2nd order
