I found good quality product more cheaper here. I installed the shocks. Did not have any problem.

Items arrived quickly - don't remember receiving any shipping notification though beforehand

So far all good.

Easy to order

This was my first order and your representative walked me through the process on the phone to make it a seamless order.

Easy navigation, wait to see how fast it takes to get it.

Very easy and good price

Fast shipping, accurate order and good communcation.

The casing on the speaker was broken, but I did have another casing to use. You only had one available, and I couldn't find it anywhere else, so I chose not to return it.
