I ordered 2 of these as Christmas presents. They turned into 1 of the hot items this year. I received an email saying the order would be delayed but would get here by Christmas. Problem was - I had to mail 1 of them as a gift. I contacted customer service and they made sure to ship 1 where I needed it to go. They both got delivered before Christmas. My husband used his when the check engine light came on during the deep freeze. It worked great! This has already saved us money by diagnosing the minor issue due to cold weather. Great company, great product, easy to use. I highly recommend FI XD.
