The order went smoothly and it showed up 3 days earlier!!

Ordered 4 Doorman TPMS sensors for my 2007 F-150 as Autoplicity had the lowest total price on the internet. Received them within 3 business days and were packaged well. I took 1 star off due to the order process. Website speed was slow and unstable.

Very easy

Fast and easy. Thank you so much.

The order shipped quickly and arrived within the time allotted. The order contained four of the same items but was shipped partially from two different warehouses. I was only given one tracking number so when only two of the items arrived I had to contact customer support to verify that the other two were on their way.

Great part, great prices!!!

shipment came on time, and was nicely wrapped.

Just received my order! I placed the order Sunday night and received it on Tuesday, super fast shipping! The SS vent caps look great and arrived in perfect condition. Thanks!

Very fast shipping! I got an email saying it was shipping 2 days after I placed my order, when I checked the tracking it was already delivered to my house! Will shop again.

Very smooth ordering and processing. Great communications.
