  • Great value for the money I would recommend it
I'll be honest I have a lot better skin tools but I wanted something that I could keep in the truck and they have to worry about people stealing this little guy is very impressive it's a full featured scanner that you use on your phone and if you are savvy enough you can get to work on a tablet and you cancel get it to work in landscape that's the biggest surprise out the box is it's really only compatible with a phone and you can't use it in landscape, I've used it on 4 general motor products I've used them a few Chrysler products and I've used it on several Fords and even a couple Volkswagens seems really good for the price and don't get scared off about the yearly renewal it's honestly a great deal with the subscription after a year cuz it's still half the price of even an entry level tablet based scanner this does all of your needs everything from oil resets injector codeine transmission relearns you name it even has some immo features for certain brands I was able to pull the pin and get a key fob working for a Chevy traverse, seems very accurate it is a little slow when you first load a vehicle but once you're into the vehicle and you're doing what you need to do it's just as quick as most tablet based systems out there, one thing I did notice is that auto Vin scan is hit or miss really depends on how it's feeling I guess cuz you can unplug it plug it right back into the same vehicle and we'll find the VIN even though it failed the first time that might be something that think car needs to work on but honestly I would suggest this to anybody looking for a full fledged full featured scanner of course you don't get topological system layout but it does show you all systems everything from the radio to the body control module to door modules whatever you want this thing will cover it all at least with domestic and some foreign stuff that I've messed with with it I haven't had one issue yet ... show more

  • Great tool for a good price
Great tool, works on every car I have used it on. Reads all codes, clears all codes, and you can reset and test/actuate just about every function your cars computer controls. I also have a Blue Driver that only reads and clears codes, but it also tells you how common the issue(code) is on your vehicle, it also gives you the most common fixes and a link to Amazon for the needed part, which the Thinkdiag does not. ... show more

  • This arrived today and has already saved me $
Absolutely amazing. I purchased the Xtool bidirectional scanner previously and returned the same day I failed to get it to work. I downloaded the app, paired it with my Bluetooth and the device even acknowledged it was paired, but the app kept saying no Bluetooth devices connected. I just replaced my ECM. So I decided to purchase the Thinkdiag2 figuring I could save some money on having the parameters reset and the key programmed plus having a quality obd2 scanner. It took a while because I was going by the parameter reset directions from the ecm manufacturer, but my engine finally turns over with the new keys, plus I was able to run an impressively comprehensive diagnostic report, generate the report to pdf, upload to my phone, then reset all the codes. I probably would've spent more for a locksmith to reprogram 3 keys than what I spent on this purchase. It's already paid for itself. ... show more

  • Essentially useless and neutered after 366 days. Cough up $$ or toss it.
Works, with iPhone, has nice features that are useful. But the price tag is too high. $130 plus tax only to have to re-up 366 days later, at another $100+ annually that adds up. Go to harbor freight, get a handheld that even if you choose not to update still functions as it would on day 1, just without updates. If you buy it and hope to use it on day 366 you’ll need to pay again or else. Can’t read deep data, like for instance ATF temp on a Toyota for trans oil level checks. It can read codes but a $29 scan tool can do that. More of a scam tool than a scan tool. 100% regret. Customer service was apathetic and I was more than disappointed that the functionality is gone after 1 year. ... show more

  • Features Missing for iPhone Users this device is for Android Users. You can renew for $70 per year
Let me say that this thing will compete with my Launch x431 SPRO3+ scanner which is around $1200. This is a lot better then the TopDon TopScan as well it does more special functions such as Transmission learning and has a ton of active tests / bi directional controls. This device is however for android users. The 4 in 1 graph or combine does not work with IOS or iPhones at all and is major feature. They mention this is because of copyright features. This means no plotting 4 wheel speed sensors at once for iPhone but for Android it works. This is why a took a star away because they mention that this feature but it doesn't work again for iPhone. But for the price this thing is absolutely amazing I have tried on it couple of weeks so far and the active tests all work for it. The graphing is also ahead of Topscan and allows you to change and look at graphs and 4-1 with recorded data and the TopScan won't allow you to do that and just plays a movie file back of the recording which is very limited. I would recommend this over TopScan because you get some much more functionality and the graphing is awesome. Plus it can do ECM Replace for Honda / Subaru and TopScan Doesn't do that and transmission relearn and keys. The reason for getting this is I bought a Launch x431 Pro3S+ 2 years ago and I can't renew it because they want $524 to renew 5 vehicle makes for 1 year which is crazy and costs 2/3 of the Scan Tool. So I bought this to replace my Launch x431. So far I have compared features of the Thinkdiag 2 to the Launch x431 and this little device can do almost as much as the x431 for a fraction of the price and at the renewal won't be $524 per year. I also got this to work on an Android Tablet even though not recoommended and it is working out so graphs and everything are larger to see. I also like it has a cord so you don't forget it in a car. It the scanner part fits in the door side holder nicely or on top of the steering wheel. I have the Topdon Topscan as well and this thing puts the TopScan to shame in features again such as special functions and the ability to replace ECM on certain models. For the price it just can't be beat and it looks like you can renew for $70 per year which is really good considering the options you get. www.x431tool.com is a way to renew for reasonable price $70. It also appears durable and should hold up. Don't full for the ones with lifetime updates like gearwrench and xtool they won't update plus you dont get key ecu coding or transmission learning. It almost looks like this has the same software as the Launch Scanner as its almost identical in the way it functions. I just wish Launch would make it so you can renew without have to spend ridiculous money. If you are looking for a scanner such as Launch x431 I wouldn't buy for the above reasons. Launch Support is also in China and they don't seem to care about fixing their software or doing anything when you submit feedback I hope for this Thinkdiag 2 its a different experience. You can't lose on this Thinkdiag 2 on the price point. ... show more
