Amazing and Powerful Tool
Given the pricepoint, this is a total game changer for the DIYer and I see this as something pros might prefer simply because it is relatively inexpensive. So that if it breaks or gets stolen, you are not out several hundreds if not several thousands of dollars. I’m not sure if it does *everything* a bidirectional S.O. tool might do, but the big tool truck brands should be on notice.

Uh… Subaru CVT relearn?
There has been a flurry of excitement online about how this tool can be used for a Subaru CVT relearn. I bought it, and that isn’t apparently possible on a 2014 Outback, a 2015 Forester, or a 2016 Legacy sedan. I haven’t been able to find more specific-year/model info online, nor the Patreon page for the individual who announced the capability. I can see the transmission module, and can see a positive indication of transmission learn status, but just can’t get to the data purge and re-learn. I can see more transmission modules on the Legacy than the Outback, which indicates the Gearwrench sees what is available to it. I put the app on a large Samsung tablet, and for the systems it does work with, it’s fine and has an easy interface. I’ve now got five OBD II scanners. I believe I’ll have to spring for a $600 scanner.

Interesting Device
I was disappointed that I only got one code! The setup was easy, download easy, insertion in OBD port (after watching a YouTube video) easy. The good news is that wasnât much to diagnose on my 15 year old Honda Civic. And yes, it is IoS compatible.

Found One That Works
Found one that works on all my vehicles. 16 Audi Q5, 12 Cadillac SRX & 06 Lexus 400h. I hate to say it out of all (4+) I ordered & tried this is the only one that worked. Yes, I could have paid 3+ times more for one but why. Hate it for Amazon and their merchants but what it is, is what it is. I therefore HIGHLY recommend the GearWrench GWSMARTBT!!!!Best bang for the buck!!

User interface could be improved.
I like it but is not as easy to use compared to a dedicated handheld scanner that doesn’t use a phone. I don’t like that I have to type the VIN because most of the times it will not find it. Was not able to read ABS codes on my 97 Acura Integra GSR but that could be the car is too old. You will have to download the diagnostics files specific to your car or special features before use. Also, linking the phone to the tool via bluetooth was a pain. I guess I will get used to the user interface after I use it more. I am used to being a lot faster with the other type of scanners. The live data on this is nice.

Decent scan tool, hard to set up
I haven’t used this device yet for anything but the most minor diagnostics, but so far I like the interface and it seems pretty powerful. I might eventually give it 4 stars, but I am stuck on 3 because I had a terrible time getting it to connect with Bluetooth. I have seen in other reviews that some are having the same issue. The instructions are very basic, which would be fine if it just worked, but if it doesn’t, there isn’t anything to fall back on. After hours of messing with it, installing, uninstalling, etc, I finally figured it out. I am using Android devices, a Samsung phone and a Google Pixel tablet. I could pair the GW no problem to Bluetooth, but it would never actually connect. Long story short, I finally thought to go into the actual app settings for the GWSMARTBT app after focusing on the Bluetooth stuff. In the app settings, then “app permissions”, I turned on “enable nearby devices”. It instantly hooked up and now works fine. There is no mention of this in any instructions. Hopefully, this info helps others. Now that I’m over this initial frustration, maybe I’ll actually like using the tool. Stay tuned…

Great tool
For the price and what all it does itâs worth every penny

Finicky at best
Product worked as intended when using an iPhone, but if a I tried to connect it to my Pixel 8 Pro, it would never complete the Bluetooth handshake. This is a rebadged xtool and is just as buggy as those products. Save your money and the headache.

The bluetooth would not connect on my new 5G Blackview Pro 9000 android 14 no matter what I did. When the OBD was installed it did send a pairing request but still no luck as I literally tried all combinations. Connecting with an old CAT S62 Pro android 11 that I had spare proved successful and then connecting to my old Samsung Galaxy 12.2″ Pro tablet was the master stroke instead of those tiny little screens this is now my go to workshop tool. I have already done an autoscan but it could not find my VIN, the option to enter it manually was a winner so I ran a scan, found a couple of issues (one of which I knew about) and sent a report to my own desktop email account where I split the monitor screen and started searching Fault Codes. Can not wait to run the Live Scan and get my old girl running like a dream. CHEERS!
