It was great

Quick and easy

I didn't favor the automatic additional payment options selected for me, such as the insurance and the 2-day shipping options. I feel that permissions should be prompted during the ordering process.

Very good!!

Fast Service

Easy to find parts with the manufacture part number. Easy check out.

Thanks

Good job

Finding the part was super easy and simple. The only issue I really had was the delay in the shipping. I paid extra for faster shipping and it still took over a week to get to me. When I tried contacting them through the chat I never got any feedback after asking questions just a "let me check that for you" then chat ended. I finally decided to email and then I got a reply basically saying the same thing. Correct part did wind up showing up without tracking update(kept showing sent to warehouse).
