I own a small business with a hard driven 10-car fleet. Not a "car guy" going in, I quickly figured out that I better learn to DIY all I could or I wouldn't last long. Got this scanner for around $60 and it paid for itself in under 3 days. Day after it arrived, engine light popped up on one 9f the cars. It took me a total of maybe 20 minutes to scan the code, google it, watch a short YT video of the repair, order the $15 part on Amazon, and then change it out when it was delivered the next day. Dozens of similar scenarios since then. OBD-II code + internet = self reliance = power and options. Even if you won't DIY, getting codes and researching before walking into a shop gives you a huge advantage.
The battery test function is better than the actual more expensive battery tester I bought before this, and the datastream capability is very useful for monitoring and troubleshooting some issues.
Every negative review I saw here was a mistaken expectation. This scanner does have a small database of generic possible causes for each code but it's not vehicle-specific or comprehensive. Isn't supposed to be. If you want a scanner to serve you full specific detail on a silver platter, you need to spring for a beefier (and more complicated) scanner. With this one, get the code, google it along with the year/make/model of the car, and you'll
be pointed to all the info you need. Another complained that they cleared the code with the scanner but the code came back the next day so the scanner doesn't work. Made me choke on my coffee. Newsflash, no scanner will fix whatever is generating a code. That is your job. Someone else included a photo of a clearly broken display and complained that it stopped working after 2 months. This unit is sturdy enough but if you step on it or drop a hammer on it or use it as a hammer, yeah that'll probably finish it for good. I've had mine going on 3 years. It's used a few times a month, been dropped on concrete more than a few times, and it otherwise lives full commando in my trunk or on the floor of my backseat, and it has never failed me. Highly recommend.
