Supper Easy!

Great service

I have not tried the product yet but hope it works well.

The product was delivered in a couple of days over the 4th of July weekend in perfect condition. I had to send it back though because it didn't fit the existing bracket on my boat. I was not able to verify specs on your website so I did not realize that I needed to order a look-alike product from another company. Their product was half the price, but I am still waiting for delivery. Your customer service was incredible and you handled the return with very little effort on my part.
