Works well, Easy to use, No Issues... Plugged right in now issues and worked great. For the Cost Spent it is a Very good investment... If a Mechanic scans your car, figure $100 bucks for starters and the costs go up in a no linear scale. Very Compatible with my 2014 Suburban, Connected great, First time, and no issues noted! Even if you are not a mechanic, this is good to have... At least you can get an idea of what you are looking at and may show you that your Mechanic is Gouging you for non-existanct repairs!

I have a very small leak in Evac system that they can’t find. Check engine light comes on 2 days after I fill tank, Replaced fuel cap. But it still comes on and Stays off till I fill up. I needed way to clear code and make sure it’s not something else triggering light. This was simple to use plug it in and it works right away. Was able to read the code and then clear it to turn off check engine light. Diagnostic code was exactly what I was told by mechanic 2 times. Great value and peace of mind. Should have bought one sooner. Every car owner should have one.
