They’re supposed to be decent “high end DIY” Scanners is how my innova rep described them when I got to meet with them at a convention. Supposedly great for the guys who know a little bit about cars. But for the price, I’ve always recommended something like the Autel MX808. A little pricier, and low-mid shop grade level equipment. Allows for diagnostics and full read out. Yearly updates for about 100 a year.
but it depends on what you’re looking to use it for.
