★★★★★ Dallas Bowling · May 16, 2026

I use my topdon pro every day at work my fellow technician are very impressed with the pro dongle my service manager just purchased the topdon master today I absolutely love my decision on purchasing this scanner

★★★★★ Christopher Wiedman · Sep 12, 2026

I am a professional automotive technician, and I use it every day. The best little tool to have in your arsenal! Definitely recommend for professional or diy use!

★★★★☆ mark · Jul 11, 2026

I think you all should offer a monthly subscription for the 22 special bundle.

★★★★★ Sean Schroeder · Jun 24, 2026

I've had my top scan for 3 years and have loved it from the first time using it. It's extremely helpful for diag and getting to the root problem. It's the only OBD scanner I'll ever need. After the first year subscription though I found it to be very pricey and wished it didn't cost so much for a subscription. Other than that it's an amazing tool I can't live without. Thank you.

★★☆☆☆ royal hayze · Feb 23, 2026

Functionality is great. The device itself and software does what it should. The almost mandatory subscription is a bit predatory. I would think you should at least be able to marry the device to 2 VIN's. That way those of us home mechanics can use the features we paid for on our personal vehicles at least. If you want to use it in a shop or to make money, sure. Us individuals who use it purely for personal use should get some of our features back. You've turned it into a $20 scan tool.

★☆☆☆☆ Lunar Concepts · Jul 8, 2026

Another half hidden pay to play service that's half-baked. All my cars are 10y old or more, and I don't need the updates. Said it covered the 2010 SAABS, but it doesn't cover the 9.3 which was available in the US. So why pay a subscription fee when you don't get the cars listed and don't need updates that don't impact the cars you drive. Save your money and get a tool that doesn't drain your pocket every year or force you to run updates every time you need it.

★☆☆☆☆ S Morrelli · Mar 9, 2026

When I bought the scanner, it said free lifetime updates and said nothing about a subscription. How are you going to charge more for a subscription than what I bought the scanner for? What a joke.
