I will use this vendor more. Prices are very competitive. I wonder do you price match?

Good service. Item doesn't fit, wrong size. Awaiting RMA to return for refund.

Prices were good, but no free shipping takes that away

It went smoothly. The customer service is the best..arrived in 2 to 3days..awesome

very easy and not complicated and no hidden fees. Thanks

Found what I needed.

I was very pleased with the product. The prices are very reasonable and shipping was extremely fast. I would definitely use their service again.

Great

the order and shipping was great. the no drill air springs went on fine on the left but the right side will not go on at all and will likely be returned. I refuse to drill if they are advertised that they are no drill.

It was easy enough to do it over my phone , I loved it

Ordered last week out of stock had to redo order again

Order 12486. Item was simple to find and the website made it very easy to navigate. I appreciated the ability to pay with paypal and email notifications gave me confidence that everything was taken care of properly.

shoping here is too easy and fast

I called to check stock before I placed order and to ask how the amazon check-out worked. The lady was very helpful. So far, So good! Received item fast and with the best pricing I could find anywhere. Thank you!

Great prices and communication, fast shipping. What more could you want or expect from a company?

Return customer with a few more future purchases in mind...best price plus quick shipping means these guys are just that good!
