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.

This ODB scanner is easy to use and helped me identify an issue with my wheel speed sensor. I had a problem with intermittent ABS error on an old BMW. I used the graph function and identified an issue with one of the wheel sensors. I had an entry-level job scanner for many years and decided to invest in a more expansive ODB scanner to see the difference. The unit is fast and was able to read my car health report much faster than my old scanner. This is worth my purchase and saves me money to take the car to an auto mechanic.

I bought this scanner to use as a general purpose cover-all unit and am very impressed. Once I set up the AutoAuth account I have with it, scanning FCA vehicles has been a breeze. I used to have to install a bypass cable which took a ton of time depending on the vehicle, but with this scanner It's plug and play.This scanner is cheaper than updating one of my big name (Snappy) scanners, and gets me more coverage than I've ever had. For the price, you can't beat this one.I have scanners from other big brands and this one has been my go-to ever since purchasing it. The speed at which I can get information from a vehicle increases my productivity and is a genuine time saver.

I've had quite a few scanners and I found this one to do all my others couldn't. It wouldn't scan all the modules in my car but I have a police car so that's understandable. It does work on all my other vehicles and it's actually fast. I like the numerous vehicle options it has and even comes with the different connecting cables needed. You can virtually figure out the codes all with one unit due to the internet compatability. I'm very pleased with the purchase.

Does so much more than my previous vehicle scan too. It picks up the VIN# and basic information then downloads the appropriate software quite simply. Very intuitive and powerful. It turns on fast and the battery last for hours. The case is very protective. I like the ability to things with this that normally I'd need the dealer computer to do. This has cut my testing and diagnosing time down considerably. There are several advanced accessories available that when interfaced with this will perform things like, TPMS, Endoscope, Battery and Charging systems, Oscilloscope, and more.
