I bought a Launch X431 IMMO to do work as a DIYer. That's pretty much my business as I flip cars and find work wherever I can. I finally, after about a year decided to try and make a key for a car that I was going to sell. I wanted to give the customer 2 keys instead of only 1 and making them purchase 1 somewhere else. That's when I found out that my X-Prog-3 would not be recognized by my tablet. I thought that would be an easy fix, little did I know that I wouldn't be able to contact anyone to help. The one time I did make contact with someone, they told me to use the tablet messaging function to communicate. Only, the messaging function doesn't work and because the subscription expired, the tablet doesn't even log into their system anymore. I would gladly buy another subscription, if they could get my unit to work, but it's IMPOSSIBLE to get any service out of these people. Another company told me that their too busy making clones of other products and selling them as something new. ?? DON"T BUY ANYTHING FROM THESE PEOPLE!! IF YOU DO, WHEN YOU NEED HELP, YOU WONT BE ABLE TO GET IT!

Scanner became useless after updates - no help from manufacturer - Do not buy !
So I bought a Launch 129X and succesfully used it to check and record all the battery and motor information of our Kona EV.

Originally, after scanning the VIN code, the unit did a system check and gave the option to further investigate all systems on the car.

The unit indicated that updates were available, so I selected this option. After it installed V52.01 for Hyundai, I connected the unit again. It began the same, but after the VIN check, I now only have the option to view ABS and Airbag systems. ALL the other functionality has disappeared.

I wrote to @cnlaunch to ask them to correct this error. 1st, they told me to use the Instant Message option on the device. My device HAS NO instant message option.

They asked for the seriel number, which I sent. I got a reply telling me to use the Instant message tool that does not exist.

I asked they roll-back the software to the previous version which worked. I got a reply to use the instant message tool !!

Recently, more updates were available, so I installed them, as surely after a specific request they would have deleted the 52.01 version and put back the v51.98 that worked. There WAS a new version.....with the identical issue to the current problem.

Basically, I had a unit that worked, and cnlaunch removed all the functionality. They have done nothing to resolve this issue in 5 months.

I have to STRONGLY recommend that you do not buy this, or any other CNLAUNCH product, as you never know when it is just going to stop working.

Bought a scanner for my car via Amazon, and after reading loads of scanner reviews I went with Launch because of their claims for their scanners.
This is their claim:
LAUNCH Creader Elite obd2 Scanner For BENZ the Same Function as X431 OBDII Diagnostic, Full System Diagnostic, 30+ Reset Function, Active Test, ECU Coding, Smart Diagnosis OBDII Code Reader

30+ reset - RUBBISH no resets provided you have to buy them, which I did another $42, still does not work.
I would advise you NOT to BUY.
No follow-up if you have a complaint or they do not respond to emails.
