Diagnostic laptop
I highly recomend this product. I am extremely impressed with how everything is layed out on the laptop there is not a single truck or peice of equipment I have not been able to hook into. This item is very affordable hands down would get this over some other scanners out there that are quite litterally tripple the cost and less effective.

Useful tool!
It has worked for what we’ve needed it for so far. We have a Cummins isx870 and have been able to diagnose fault codes and clear old codes. No problems so far!

Diesel Diagnostic Laptop Scanner Truck Tuner Heavy Duty *2026 Kit Tool
very satisfied with the product was everything they posted I’ve only had it for 14 days used it several times and very impressed between international Kenworth and a Chevrolet car successful The ability to do such scanning and such heavy detail really cuts the diagnose time down and narrows it down for quicker repairs, and cheaper repairs. Don’t know how I survived without it for all these years. and the gentleman I spoke with with the tech department was very polite and very knowledgeable of the product. If I could reach the phone and shake his hand, I would.

2024 Scanner
I can say this is the best purchase I've made for my Diesel shop and for my trucking company. I've had other computer systems but this one is a all in one for equipment my shop deals with even down to Ag and construction equipment. For some of the programs to run them you have to have additional adaptors to go in-between the OB 2 port but still better the all the systems with Snap-On or Mac tools I'm really impressed and this system has already saved thousands in less then two months time.
