I got my order on time and the parts are quality.

thank you

I paid for two day delivery and it was like 4 days before l received and no refund was offered.

Simple and easy

I was very satisfied with the ordering process; however, I paid $10 extra to have it delivered in 2 days. It was ordered on Friday and not received until the following Wednesday. So do not waste your money on faster shipment, go with the free shipping instead.

I ordered the part, but never got any shipping info or updates, the package just showed up, would have been nice to have gotten an alert that the part had actually been shipped. Other than that everything was fine, I got the part and my customer was happy.
