First, the product was very well packaged, and also very well protected in a case. Very pleasantly surprised by the number of connectors, which didn’t appear in the original advertising. It came ahead of schedule , and the driver went above and beyond: I have used several of these tools, usually on the lower end, which generally required more testing to verify or disprove results. This tool gives comprehensive reports, and goes into flattest detail in evaluating the condition of your vehicle. Definitely a pro level scanner. It is noteworthy as to how solid this unit actually is. I would definitely say solid and well built. The screen is extremely clear, and the tool is very intuitive , well thought ought, and it is both logical and easy to use. I purchased a protection plan with it , as I would highly recommend as well, just because of what it is and the environments it is used in. It has already paid for a quarter of itself , and is extremely valuable if you are going to do the work yourself, or want to know what you are getting into before you bring it some place to have the work done: the only negative that I have observed is the length of time it takes to update: I love the wireless feature, as well as having a wired option, either way it works very well. It also prints reports , which are extremely detailed. The battery life is excellent on the unit. While I personally won’t use it very often, as opposed to a shop, I will be using it frequently . I would highly recommend this unit. While I am new to Launch, I suspect this version is far superior to most of their other models. I would love to see them come out with an IOS version to bring on road trips. The bidirectional functionality is excellent. It is noteworthy that the unit and port connector work together perfectly. I have not experienced any lag time. I found the reviews praising this unit to be accurate and reliable. Of course time will tell the long term reliability, and update potential, but I believe, at this point, that this is the next best level of technology, and it will be upgradable.highly recommended.

We recently purchased the Launch scan tool because we wanted a budget friendly option next to a $7,000 Matco scanner that the tool truck guy was really pushing us to buy. We demoed the Matco unit for a few days and we were not impressed. However after using this Launch scan tool for a few weeks now, we are extremely happy with the tool. It’s allowed us to perform ABS diagnostics on the new Jeep JL Wrangler platform when the Matco unit wouldn’t even connect to the Jeeps. It’s allowed us to do full master code resets and clear out stored codes that the other scanner wouldn’t. This little unit has saved us numerous times when the big expensive tool truck models wouldn’t do what we needed them to. We also own a Snap On Versus Edge and now all our techs are preferring to use this scan tool because the user interface is easier to use. The menus make more sense and it’s faster. We give the Launch Scan Tool 5 stars for effectiveness, value and ease of use.

I'm a DIYer that may have too many cars and also likes to help friends when I can. This scanner is very feature packed and has already helped find some BCM codes on my Nissan Pathfinder. I will be digging deeper into the resets and other functions on another car when the time permits, but already this appears to be a better unit than one I bought before at a similar price point and had to return because it wouldn't connect to other modules. I like how the scanner is portable around the vehicle while the module is plugged into the OBD port. The screen is easy to read and responsive, it picked up my home network and updated very quickly, especially compared to my other experience, and I was able to connect to my phone hotspot for mobile troubleshooting.
