Bought an adjustable proportioning valve. Autoplicity was the cheepest source by several dollars. Haven't got it yet, but I did get an e-mail with-in 24 hours that stated that it had been shipped. As long as I get what I've ordered I would say that they are worth giving a shot.

I ordered a chrome brake light cover from Autoplicity 3 days ago and received it today. Their add showed the piece I wanted clearly and it arrived today exactly as I expected. It looks great on my new Dodge truck. Thanks for the great service!

The Curt Class III Hitch Receiver installation on my vehicle was simple and easy. The hitch is of good quality. I would recommend this product. Autoplicity was prompt with the order process and delivery.
