ELM327 OBDII Car Auto Diagnostic Scanner, Professional Wireless Bluetooth Scan Tool Failure Detector, OBD2 Engine Fault Code Reader for Android Windows, Car Accessories

it has its problems, like frequent disconnection. but if you're actually reading OBDII codes for five bucks, you cant conplain. it would be spoiled to expect perfection at this price point

Bought the two pack so I could keep 1 in my truck, and use the other to monitor stuff on my 2016 KTM 390 Duke with the other. Well, 1st, it took over a half a frustrating hour to get the things to pair with my phone & the Torque Pro app... Did this in the garage on the KTM, and FINALLY got them to work on it... Move over to the truck, no dice, they will not communicate at all with the truck ecu... Waste of time, money, and a lot of aggravation to boot. Thought they would be the exzct same as the one I had to replace after 10+ years, since they looked identical. Well they are not! If anything, I expected them to work in the truck & require a bit of fiddling on the bike since it has newed CAN messaging, but this was the complete opposite... What a pain in the butt!

Works good with multiple apps of of playstore.

Not working, really bad quality with lots of solder trash inside causing short circuits.

They work with GM vehicles to pull codes, but they are slow. Not good for apps such as Torque Pro unless you don't mind a 5 second delay. The cheaper OBDII device aren't good for that.

First off, the pin is 1234 BUT you have to enter it IMMEDIATELY after plugging it into the OBD2 DLC. The device comes with a disk but that was not as helpful as i hoped. I bought it to use with a specific locksmith related program and it didnt work out for me. It does seem to work fine with other apps as a scanner. It does do alot for the price.

I am pleased with this product. I needed to get my car smogged and my mechanic said I needed to drive 200 mile and 15 warmups. He said that would take about two weeks! I didn't have that kind of time and went to YouTube and learned I could do what I need in less than an hour. This ELM327 unit paired with Car Scanner app on my phone showed me everything I needed to get all the test to run and I got my car successfully smogged the following morning! You can spend a lot more money on other readers but why unless you are trying to use coding options.

For price product is a great deal. The problem is it comes with one CD containing old outdated software that wouldn't install on a Windows 11 laptop. Ended up downloading and paying for software. 😡 UPDATE. Used both once then nothing stopped working.. 😡 😡 Suggest not buying. Find something up to date.

Buen producto, buen precio y con muchas funciones.
