love the price wow!!!! thank you guys for being around I just saved over 50 bucks!)

A bit skeptical because it seemed to good to be true but was in fact the product perfect condition! Thanks!

Easy to order, excellent sale price with free ground shipping.

This was the best price on a set of 4 Bilstein shocks in the net so that's why I purchased from THM!

Helmet is as described and fits fine, however, it's so huge I cannot use it in the car as intended. Some reviews call it "Marvin the Martian" looking. This is generous. It's more like Marvin the Martian on steroids. Will need to return and look locally for a helmet.

Easy ordering

.
