Fast shipping, product was excellent .

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Smooth transaction, very pleased

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.
