  • Perfect OBD
I have used different obd devices before, but since my vehicle is hybrid, not every obd compatible. That's why I chose this device. First of all, you can see all internal menus of the device from the pictures. My main reason for buying was that I had to measure the voltage of the hybrid system, and I took care of my problem very efficiently and quickly. Voltage measurement on other devices seems stable for 3 or 4 seconds. Thinkobd shows instantaneous readings and shows a measurement approximately every 0.5 seconds. this means a high precision device. Also, one of its best features is that it has a menu that shows what the error codes mean. Again you can see from the pictures. It is already able to delete errors. One of the other important features is that you can see if you can pass the inspection. You can see this from the pictures. I used it in 6 different vehicles, two of which were hybrid and I had no problems. It is very simple to use. Just connect it to the vehicle. Also, we cannot update the firmware. I tried to explain everything. If you are solving the problems of your vehicle yourself, it is a very good product in terms of price performance. If you have anything to ask, I will gladly answer. ... show more

  • Entry Level - ThinkOBD 100
The Good: This scanner is a good entry level budget scanner under 40. Has a nice fault code library. Good for basic code checking and great at prepping for emission tests. Quality and durability are good, but will fail if you're someone who abuses their tools. Screen is legible and bright enough to read in broad day light. Vehicle's this scanner has worked on: 6th gen civics and 6th gen chargers. Was able to prep my cars though the I/M readiness function and swap out an EGR valve and pass emission test first try. The not so good: This doesn't function unless car can crank and start. Doesn't read TPMS, ABS, and battery/electrical codes. Which makes it entry level. If you're looking for a entry level code checker and a emission prep tool this is it. Anything other than basic and it's out of it depth, but still a great tool for the money. This has been after 1 year of use. ... show more

  • Not expensive, handy easy to use.
Not expensive, handy easy to use. Can do basic diagnostics and resets for testing issues. Update was easy to firmware. If you want something to find out what is going on this should do the trick for OBD2/ EOBD equipped vehicles. Feels surprisingly NOT like garbage / toy - I'd rate it medium class simplistic tool. For me the issue I was looking to find out was vapor leak small / major.... turned out to be gas cap seal needing some work on a 2010 vehicle. ... show more

  • It works
In 2010 I purchased an Actron scanner on amazon. It still works. I purchased the Thinkobd because it is so much smaller and easier to use. I tested the Thinkobd and it works just like the Actron, except the Thinkobd is smaller and with fewer keys is much easier to use. I used the Actron about a dozen times over the 10 years I owned it and I expect the same with the Thinkobd. With a permanently attached cord and being 75% smaller the Thinkobd is easier to handle. The functions are easier to access and the updates work. The Actron did not have updates and the Actron website never worked. The update was well worth the money. One of the best things I paid $90.30 for the Actron and around $30 for the Thinkobd. Smaller size, smaller cost, less keys, easier to use you cannot lose. ... show more

  • Decent for Basic Diagnostics, But Limited
This scanner is okay for reading basic engine codes, but it has some limitations. It quickly pulled the check engine light codes on my car, which was helpful. The screen is clear, and it’s easy to use. However, it doesn’t provide much detailed info beyond the basic codes. It also lacks advanced features like live data or manufacturer-specific codes. If you just need a simple tool to check why your check engine light is on, it does the job. But for more in-depth diagnostics, you might want something more advanced. Overall, it’s fine for casual use, but not the best choice for serious troubleshooting ... show more

  • Great Engine Analyzer for the Price.
Nice analyzer for the price. Menu display made unit easy to use. There are many online videos on how to use the unit. Unit displays run time graph on engine load, RPMs, coolant temperature, and car speed. I used this unit to check an engine light on my 2009 Honda CR-V. Engine light was on due to gas cap not completely tightened. ... show more
