Very nice inexpensive OBD reader. I keep it in the car for any lights that show up. Simple and effective.

Everyone should have one of these in their glovebox. It does exactly what it says—plug it in, read the codes, and figure out what's going on with your car. No more guessing or paying someone just to tell you why the check engine light is on. Easy to use and works just as advertised. Already saved me a trip to the mechanic. Great peace of mind to have on hand.

It’s great for just starting out using an OD1. It’s taught me so much about my car to the point that I leave it plugged in 24/7. !!! It’s very informational during any said drive long or short!! There are some functions that I think should work but don’t give me any data but in general I’m content with this scanner!!

I had zero experience with scanners before buying this one, and I found the issue in less than two minutes with this thing. Easy to use and read. Works like it says. Definitely worth the money.

Good little scanner. Makes life easier so you won't have to worry if the mechanic is lying to you.

Works as described. Quite reliable and accurate . Do recommend.

Great value for the money, this has already paid for itself several times over with its quick diagnostics and ability to clear error codes. I also love the graph of live stats for RPM and speed
