Not the part I needed, but it was not their fault, specified what I needed on ebay search and the one they recommended does not fit .I blame the Ebay search function and not Autoplicity. The item arrived on time and was well packaged.

Awesome prices, easy checkout, thank you so much for the awesome experience!

part fit like original, installed plug and now all my fan speeds

So far so good

perfect transaction. shipping fast, part fit. don't get any better.

Great price for the product, fast shipping...Completely amazed by this seller. The rack was delivered to my door step in just a few days and the price was unbeatable. I'm really satisfied by the service and happy to have finally found a bike rack worth having!!!

Ordered on the 4th, Paid for basic shipping, got it on the 6th. Hard to complain with those shipping times. The only problem I had was I didn't get any confirmation of shipping till the day it arrived at my house. Other then that, I would buy from them again!
