In all I'm very happy with how the product works and the delivery time and communication from Autoplicity

You had what I needed and at a Great price

easy

Thank you for your prompt service.

Easy peasy

Really easy! I found what I wanted (needed) and it was affordable and worked perfectly.

Surprisingly fast service

easy

Best Price I could find, fast shipping. I shall return!

Lowest prices around the web and excellent customer service. The only real issue was the wait between placing the order and when it was shipped. Took 4 days but I chalk that up to the large amount of business they due to their prices being so competitive. For the lowest prices that I've seen I didn't mind waiting a bit longer!

Very fast shipping and product was secure in package to avoid damage....will be ordering from autoplicity again for sure. Also the price could not be beat.

Superb company! Autoplicity had the lowest price, shipped it quickly, and it was exactly as advertised - couldn't ask for better results!

Fast shipping. And great cust service.

Please send it in the Black color
