5 Stars Great Solution

Larry from OR wrote (January 30, 2015):

I purchased this set of roof bars for my 2015 Subaru Forester. It fills the need for transporting all those oversized building material buys for the home projects. Easy on and off, clear readable instructions, great solid feel and secure fit. I took a short drive with the bars installed and only heard an occasional slight rattle on our well used streets. This is a solid, good looking, economical solution to the high$ factory bars and the name brand offerings. I will recommend it to all my friends.

Works fine on my Subaru Forrester. Initial shipment had a lock problem with one end of one of the cross bars. The manufacturer replaced it immediately.

I ordered this for my 2014 Dodge Journey. These are an economical addition for me to haul my kayaks. Shipping was extremely fast even just a week before Christmas. Thanks for the great product.
