Had mine a week after I orderedand paid.He was the only one that made a 300a for my vehicle.I did the research and seen a few bad reviews but I also seen good ones so I took a chance.I called him not email and got through on the 2nd try.He told me what he could do and what price.The lifetime is an extra $99.But if you get the amputator series it comes with a 1 year, as well as a chance to exchange that one towards another vehicle should you sell that one.All in all I am pleased with mine.Email was kinda tuff getting a respose but I did.I just called he gives you his shop number if you have any questions?I did call him a couple times with questions I had to presistant with the calls but never took longer then 5 trys to get him.Just leave a message I found that helps.
