The delivery service was total mess the boxes were damaged and one of the nuts was missing .

I'm a stickler for finding the best prices on my purchases, while also making sure that the products I buy are legit and not some cheapo knock-offs.<br>I did my homework on the Clutch Stage 2 kit I wanted for my Spec V and found that Autoplicity had the best price anywhere, even a spot where I had 10% off came out to be more expensive.<br><br>I received my Clutch Stage 2 clutch kit pretty quickly (about 1 week) and everything was as expected.<br><br>Overall I would rate Autoplicity a perfect 10, although I did not have to contact their customer service or initiate a return, so the '10' would be on product selection, communication, website experience, and overall feeling that I got the best deal out there.<br><br>Thanks!

Ordered a Simpson helmet on Monday afternoon, received tracking on Monday evening and will have the product on Wednesday! Quick service! Also would like to mention that the price was the lowest of anywhere I looked up.

Great website and the ordering was easy too. I like the way they show the full price including shipping and tax. Got the confirmation immediately and the shipment notification the next business day. <br>

Great seller! good communication between autoplicity and buyer!<br>Also very quick to process and send out product! Got order within 6 days standard shipping! Will purchase from again!!
