As a professional mechanic with over 10 years of experience, I can confidently say this OBD2 scanner is one of the best I’ve used in my shop. It’s reliable, accurate, and fast – three things that are crucial when you’re diagnosing multiple vehicles in a day. The interface is intuitive, and it provides detailed data on a wide range of systems, from engine codes to ABS and SRS diagnostics.One of the standout features for me is the bi-directional control, which allows me to actively test components like fuel injectors, fans, and throttle. It helps me pinpoint issues much faster than other scanners I’ve used in the past. The live data stream is incredibly useful for catching intermittent problems, and the graphing function is a nice bonus.What sets this scanner apart is its compatibility with both newer and older vehicle models, making it a versatile tool that I can use on anything that comes into my shop. For the price, it’s hard to find a more comprehensive and dependable OBD2 scanner. If you’re a professional looking to add a top-tier diagnostic tool to your arsenal, this is definitely worth the investment.

This this is great! It scans every possible system in your truck, let's you test different parts like window relays and many other parts to help troubleshoot issues. I had a generic scanner, Chinese, it wouldn't give me details just codes I didn't know anything about. This scanner gives you a detailed explanation of what's wrong, linked to wifi it will even send you to YouTube for repair videos. I had a few transmission pressure switches that needed replaced, I was able to get the parts on Amazon and do it myself saving at least 600 dollars on a shop. My transmission is now fixed.Scanner paid for itself in one scan and issue.Now I have something beyond reliable that will last forever, it's built tough for drops or accidents with rubber all around it. I even found a screen protector for it on Amazon.I would recommend this scanner to anyone I know and would definitely buy it again. Free updates for a few years too. Probably around 100 different car manufacturers in its system so I would almost guarantee it will work for you and your friends, mine always need help lol.

I’ve been using this Topdon bidirectional scanner for a few weeks now and it has absolutely exceeded my expectations. As a mechanic, I needed a reliable scan tool that can do more than just read and clear codes — and this thing delivers.The interface is super user-friendly and fast. I was able to perform active tests and control components like fuel injectors, cooling fans, and electronic throttle bodies with ease. It even supports special functions like ABS bleeding, TPMS reset, and DPF regen on supported vehicles.What really impressed me is how well it handles bi-directional control — I’ve tested it on a range of cars and trucks, and it hasn’t let me down. It gives detailed live data and graphing that helps with deeper diagnosis too.The updates are simple to install, and the build quality is solid — it feels like a professional tool without the insane price tag.Highly recommend for techs and DIYers who want something powerful without breaking the bank. Easily one of the best investments I’ve made for my garage.

I purchased this scanner for my dealership to do more diagnosis in-house. First impressions are that the unit is very high quality and easy to use. The hard case and interior foam compartments are very well done. It was easy to connect to wifi for the first time and download available updates.A listing of vehicles I have tested it on so far:2001 Jeep Cherokee 4.0: would not auto recognize the VIN so I had to manually enter it. I was able to use bi-directional controls to command an EVAP component and the cooling fan.2010 Ford Expedition 5.4: Auto VIN recognition worked and it was able to access all modules including air suspension codes and audio/entertainment system2009 Chrysler Sebring Convertible: Auto VIN recognition worked and it was able to access modules for airbags and BCM. Unfortunately, I was unable to access bi-directional controls for the convertible top, which is what I was primarily interested in. It could access the module and identify the trouble codes related to the top, but did offer the option to use bi-directional control2006 Chevrolet Cobalt: accessed all modules and performed oil life reset.2006 Ford F-250 5.4: accessed all modules and commanded RPM and intake runner activation2006 Ford F-450 6.0 Diesel: accessed all modules and commanded VGT turbo vane activation and RPMOverall, it seems to be able to access most modules across the brands and vehicles I have tested. I’ll edit this review as I scan more GM vehicles. My primary complaint is the inability to command convertible top operation on the Chrysler and the emissions readiness test indication is not clear. I have other scanners that will simply provide a green light if the vehicle will pass emissions, although this may be more related to my inexperience with the unit. I’ll give it a 4.5 out of 5.
