  • *****Launch X431 Master

    By Nutsaboutcars

    Item arrived this morning looks great. Been in the motor trade for 15 years and this tool is an absolute must if you own a garage

  • *****Launch Master 5 Star

    By Simon King

    Brilliant piece of kit and much easier to use than other top range tools like snap-on. No silly keys involved. Have to give 5 stars here to both Launch for a great tool and also Diagnostics4u for the service great stuff

  • *****great price for latest model x431

    By James O'hara

    Hello I'm just writing a review to tell you guys the tool works fantastically and I am really pleased with the price I got. On the down side I did buy a Super 16 Connector as well but these, I can now see, are the latest version Launch X431 Masters which already have the Super 16 Connector built in. So for anyone buying this and thinking of buying a Super 16 Connector to go with it you don't need one they are already installed in the tool! Excellent item all round though top marks

  • *****x431 review

    By Happy

    Sure made no mistake with the latest launch x431 product. Accurate diagnosis of the complete vehicle. The "Help" option is a great assistance to the mechanic on how to go about the repairs. Highly recommended.

  • *****Get One!

    By S & C Motors

    A friend who has his own garage bought one of these earlier this year and at the time I thought I would wait a few months before I got one from these people. One of the reasons was, I wanted to make sure he could get updates because another friend got his Master from China last year but he still cannot get any updates and the seller keeps making excuses.

    I did buy this tool after nearly 3 months and I registered the tool and downloaded updates twice so far from the Launch main site in China, no problem. So if you're worried about updates, get one of these Masters and do your own software updates. I have made very good profit with this tool since I got it because it's brought in more business. Other garages give me diagnostic work now. Thanks

  • *****Technology at its best

    By Wallace A.L.Lawson

    This master piece is really a modern day tool.for today's engineers and technicians all over the world,since its been equipped for a wide range of automobiles.A ONE STOP SHOP tool.

  • *****Definitely Good

    By Alan Oakes

    Bought my master here about 8 months ago now and I use it nearly every day. No complaints so far. I must say these are good tools which seem to do more than most of the others I have tried.

    These are definitely easier to use than some of the other pro tools, you don't have to keep putting information in to access diagnostic systems and the menu is easy to understand. I know I will buy another Launch when the time comes.

  • *****Professional Tool

    By Harold B.

    I'm pleased to say it arrived in the states within 3 days. I've been looking for a tool for my business which covers wide range of cars and this hasn't let me down. I would recomend it to anyone looking for a professional tool and the price was really good compared to other places I looked. I will definately be back for more tools.

  • *****better then snap-on and bosch

    By Richard Munroe

    Bought this launch x431 tool to use in my garage after a friend recommended it to me and I am very pleased with it. Came with the full kit and covers a huge amount of cars and systems especially on the American cars which my snap-on doesn't do very well. These guys offer this tool at a great price and in case anyone else reading this is thinking what I first thought I can confirm these are the genuine tools. Very happy thanks

  • *****Amazing bit of kit

    By Yorkie

    I've been in the trade over 20 years and i've tried all the pro tools going but this really is the BIZZ. I can't believe It's that simple to use and does more than any other diag tool i've come across. You can see why it's called the MASTER. Well Pleased!! CHEERS!! my mates want these now:)

  • *****A Real Bargain

    By Geoff Smart

    Still can't believe I picked up a brand new version master for under a grand well impressed. Was a little worried it might be a copy but received it and downloaded all my updates from Launch website www.x431.com. (With the help of D4U staff so thanks for that).

  • *****x431 master 4

    By Craig elam

    excellent device, has more than paid for itself in a few months, we are a non franchised dealer and Launch machine has a huge coverage, great service from Dignostics 4u , helped me set up my account with launch and download software.

  • *****Launch x341IV

    By Manus Mooney

    Fast delivery and excellent after sales service from John, very helpful with the software download
    Very easy to use the X431IV and a vast improvement on my old diagun II

  • *****Definitely i recommend

    By Michel Da Costa

    I've never owned a diagnostic machine before, but i'm glad that i choose this one.
    After research in online i ended up phone diagnostic 4u by explaining what i wanted and expected from a diagnostic machine their salesman advised me to choose this one.
    Simple to use some programs are the same as the dealers, i already recovered the investment.
