Best price I could find for a programmer for my Jeep. Took a few days for the order to process as shipped but they did notify me that order would process within 24 business hours.

I used a coupon code that was said to give me free shipping, I don't see any charge fire shipping until the very last page, then $10! Wow lucky I really need these

Good

I like the cost per unit, but the shipping is a little high

My first order did not include all parts. I'm ordering a different part number now. The seller is giving me a discount due to this inconvenience. We will see how it goes.

Easy site to navigate and nice prices! Installation was ad avertised-took a little lo0ndre than an hour before I was on the road!

Good so far

great price for this product. Just what I was looking for. thank you I will shop here again.
