These Terminator X kits include a USB/CAN tuning cable instead of the 3.5" Handheld LCD, these kits require the use of the free Terminator X Software for initial setup.

Great Denim jacket!
I purchased a 2xl for my husband and it's a great quality and price. He really loves it. It's a good stretch and he's able to place a hoodie or a thicker shirt and still be comfortable if need be. Will be purchasing him another color of this jeans jacket.

Good Value Denim Jacket With True to Size Fit
Great denim jacket for the price. It feels durable and well made, though the quality is not quite on par with higher end name brands, which is to be expected at this price point. The fit is true to size and matches expectations. It is comfortable out of the box and, like most denim, should become even more comfortable as it breaks in over time. The arm length runs slightly long, but if you usually find sleeves long on jackets, this one will fit similarly.

Great base to add patches to
I've bought this jacket twice now (lost the first one...). Great base for my DIY patch jackets. I buy an XL even though it's a size too large for me. It's a standard denim jacket, not much to write home about. Good pocket size, and I appreciate the functional chest pockets.
