Launch X431 Diagun IV Reviews:
Review 1:
Has great software easy to use and bidirectional capabilities. For the money its well worth it, I watched Keith from New Level Auto, and Ivan from Pine Hollow Diagnostics use it and thought if its good enough for them then it should work for Steve at SAG. So glad I purchased the Diagun IV as I needed a bidirectional scan tool with powerful software.

Review 2:
After close to 3 months of use I can say this scanner has more than paid for itself and it has capabilities almost exactly like my $2800 Autel. Basically it has all of the same tests the Autel does and when I have a few minutes to poke around in the tool on different cars I go through the menus and see what other functions are listed and let me tell you this tool does so much for $500ish dollars if it broke tomorrow I'd buy another one because I don't know of anything out there that will do this much stuff for this little money. I still think the hardware could be improved but if you're buying something else you're paying too much.

Review 3:
I love this thing I use it on every car and it always works. Replaced multiple other scanners that were only suitable to a specific marquee of car. Now this lets me be helpful to my friends and family who don't own the same brands as I do.

Review 4:
We recently purchased this tool as an addition to the scan tools we already own, including some manufacturer level and other aftermarket tools. I have to say that this Launch has been a pleasant surprise. It has a ton of capabilities and functions, that some much higher priced tools do not have. I find myself using it all the time now and love the fact that it is small and capable. If you are looking for an all around scan tool, I highly recommend this one. For the price point even the DIY'er should think about this tool as a must have.

Review 5:
Decided to purchase the Launch Diagun and give it a try. I already have an older OTC and new ADS 325. 325 is up for first year subscription, $900. Hmmm. I've only had this for 4 days. Ordered on Sat, received Sun. Tried on my own Honda, SRS light, no problem. Monday-Wednesday, have used on about 11 cars. On a 2011 BMW, it also gives you corresponding "OBD" code.....i.e. BMW DTC 14202 - P0302 misfire cyl 2.
