Easy transaction

pretty good-great product with good delivery time.

Good availability and good price.

their write up about the product was slightly miss leading being that it was saying that the part went to the wrong car. But the part number said it was for a different car. <br><br>But hands down they had the best price and so far seems to be a great company. I would purchase from again. It would be ideal if they offered more in the sports compact area though.

So far so good

Nice site

quick and easy

All good so far. Could be a little clearer about if the order will include needed any additionally needed hardware for install.

Great price for the product, fast shipping...Completely amazed by this seller. The rack was delivered to my door step in just a few days and the price was unbeatable. I'm really satisfied by the service and happy to have finally found a bike rack worth having!!!

Best price no problem making order. Jesus is Gods gift to those who would believe

Great value, hope product is correct and new
