Order 12486. Item was simple to find and the website made it very easy to navigate. I appreciated the ability to pay with paypal and email notifications gave me confidence that everything was taken care of properly.

Product was the cheapest I could find. One other store was cheaper but did not have my product in stock. Autoplicity shipped within 2 days and the product arrived as described. I am happy with my purchase and would do business with Autoplicity again. The only thing I marked them on was that I wish they shipped within 1 day instead of 2.
