Extremely impressed with Autoplicity!!!! I am a very loyal Amazon customer and ALMOST paid a 20% premium on my Thule bike rack to go with old faithful. Very glad I didn't, as I saved $50 and received my product with free shipping FASTER than Amazon Prime!!!

Excellent service and communication.

I got the items exactly as described with VERY fast shipping. i highly recommend them to everyone. And I will definitely be shopping there again!

Great prices, clear information and fast shipping!

Great price. Very happy with order. Will buy from them again.

Best price for an expired item around, though more options in shipping would be appreciated. Ordered saturday night and item shipped tuesday morning, saved about 30% off of the originally planned purchase price. Definitely will use them again in the future.

Thanks for the great price

Super fast shipping, exactly as ordered, no drama, problems or complications

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.
