Awesome
So first off, I took one for the team. Just in case anyone else is wandering it does not work on vehicles. Just semis. Which is great because that’s what I bought it for, but I was curious to see this thing in action and hooked it up via the adapter (that’s what I thought it was included for) and it almost wiped her computer. Anywho works awesome on my semi! Great product!

****DO NOT BUY*****purchased this product over a year ago and it worked great for regens with no monthly fee. As of last update they quietly changed the terms where tou have to pay $30month to use it.. now I have a useless piece of plastic for 350$… THIS COMPANY IS A JOKE…COMPLETE FRAUD******DO NOT BUY!!!
Cedric and Cheryl Young –
Works!!!!!
All you have to do is follow the online manual. It will clear codes and do a regen. I have a 2014 Cascadia with a Cummins ISX-15. It pays for itself immediately!

Changed terms after purchase
Now requires $30 per month to do regans.
