OBD2 Code Reader
Problems connecting to the code reader each time I got into the car. Unit didn’t display RPM and did not detect an error code while it was displayed on my dash display.
patman –
Plug and play
It’s literally plug and play, super easy to use. My jeep had a check engine sign and it very quickly showed me the error code. I am a car maintenance DIYer and it was super easy to use in my opinion.

Good scanner
I got this scanner after having a Bluetooth one that no longer worked with the version of Bluetooth that I had. This is good because I can keep it in my garage and have a way to check codes on the car without having to worry about versions. It works well and is easy to use.
antipode –
May not work with your vehicle
A Chinese company requiring location permissions as well as scanning nearby objects. Not a huge issue for something that you normally run only while troubleshooting a vehicle, but in this case the scanner was detected and connected via Bluetooth but app apparently doesn’t work with all vehicles, as it refused to go further. It’s possible it doesn’t work with electric cars, as those are what I own.

Stopped working during first use

Not worth the headache.
The cost of the app isn’t worth it. The don’t tell you the cost of in app purchases.
Paul –
Easy setup and use
This was so easy to set up and use. It connected to my phone (iPhone 15 pro max) without going into settings and linking them. It cleared up a moderate code which helped the truck clear the red code by itself. I anticipate this saved me at least $700 in repair, at the time being.
P. Johnson –

Glad I got this!
I bought this scanner because I got the feeling that my mechanic was overcharging me every time I bring my cars to the shop, I really wanted to know what’s wrong with the cars before I bring them next time
Arron –

delighted not to have to pay $100 every time a mechanic takes a look at my car. Now i can see everything on my own and clear the dash when needed. It helps understand what the car is telling you and is very simple to use.

Robin B. –
Simple and useful
Was simple to use for the first time, and did exactly what I needed it to…give me the codes of why my truck had check engine light on. Super cost effective option, better than driving to your nearest auto zone to have them do it.
Jersey –
It scans
It would not clear the code. I tried 10 times nothing. But it is very informative once you learn how to use it.
Matthew T. Herman –
Great scanner works well
The scanner works great and is very easy to use. I love the size and it’s very compatible. Good price
JenGarz –
Inexpensive and works great
I use this one when I don’t want to pull out my bigger code reader. It works great and seems to be very convenient. I’ve been using it for about three months now and would buy another one if it gets lost or damaged. It’s cheap enough that I wouldn’t mind loaning it out to a buddy.
Diego –
Easy to Use & Works Great
This OBD2 scanner is a must-have for car owners! The Bluetooth connection is fast and reliable, and the app provides clear diagnostic info. It helped me quickly identify an engine issue, saving me a trip to the mechanic.
M-Zoom –
Worked as advertised
When it arrived today, I had to try it out. First, I downloaded the app for my iPhone and then went to the car to plug it in. It found the ‘check engine’ code in the car and gave a very detailed explanation of the code and links for additional information, which I could send via email or copy to the clipboard. I don’t need to drive to the auto parts store to borrow their reader to see the code. This is why I made the purchase. The added benefit of monitoring the car while running is a bonus. At less than $20, it is a very handy tool. The smartphone app coupled with the scan tool makes it so much better than the older handheld scanner. I highly recommend this product if you want to know about your car.
Claude –
Must have took
Compared to my wired obd tool this had other features and it’s a little easier to use. Added feature is the mode that tells you how you’re driving. Hard stops and hard accelerstions. I don’t have any fault codes so I can’t comment on that. It was very easy to pair with my phone. The only negative is that it does not read a cars VIN
Bob Kauffman –
Functional
These OBD2 scanners are always good to have. I’ve lost some over the years so I always try to get affordable units because they’re enough to check codes without having to go by an auto store. This does everything I need without getting into the multi-hundred-dollar units and heavy-duty equipment they have at the repair centers.
Steven Edwards –
Easy to use and read
This device is easy to use and read. No worries using on different vehicles.

Evan H. –
Great for the Price
Is this a super expensive computer that the dealerships have, well no. Does this do more than I expected and works well right out of the box for an amazing price point, absolutely! I love how small this is to just store in a tool box or even glove box and boot it up quick and easy to get a diagnostic when I need it. Highly recommend this product for simple and quick diagnostics on your vehicle.
