Very pleasant. Would appreciate more info on product.

First time

Easy. Thanks.

Fast and easy, great price

Bought the Swagman XTC4 bike rack. You need to update your pictures to show the new cheaper lighter weight black hold down ratchet mechanisms. Your picture shows the heavier gray hold downs not the new black ones. I decided it was not worth sending it back.
