Esta muy bueno

I got this scanner and just tested it. It connected to my 2021 Honda CR-V with no problem. A couple of things. There's information in the manual on how to upgrade the scanner's software by downloading an executable from elm327.com. Note that as if August 2025, the executable is a Windows executable, so if you only have a Mac (with no Windows partition), you won't be able to upgrade the software. Also, the scanner is made in China.

While my car didn't have any errors to read what they were it did have several warnings that this also noted, as such it appears to be working as intended. I was able to view live stats from the car while it was running, which I might not fully understand what it all means I am sure if there is an issue I can find the appropriate information to compare against. No complaints here.

Walking into this purchase, I had every expectation that I was about to add another sluggish, barebones diagnostic tool to the growing pile of sub-$30 disappointments. But this thing is shockingly fast. In a world where budget scanners tend to crawl through protocols like dial-up, this one connects instantly without fuss. No manually selecting communication settings—it just works. It pulled the VIN and calibration data with ease and, despite having no active trouble codes to chase down, I was able to stream live data without a hitch. Engine load hovered at 16% with the AC running, dropping cleanly to 12% when shut off, all within a responsive window that felt nearly real-time. Oxygen sensor voltage readings? No problem. A barely perceptible one-second delay kept everything moving smoothly, which is a far cry from the sluggish updates many budget units serve up. If I had picked this up blind and been asked to estimate the price, I would have said $40 or more. The display is sharp, bright, and easily readable, making the experience feel polished beyond the price tag. If durability holds up, calling this scanner a must-have is an understatement. At $20, it's the kind of find that makes you wonder why other manufacturers are still getting away with selling overpriced versions of the same thing.

This reader is equipped with a user-friendly interface that links quickly to both American and import vehicles. I chose this particular product for its broad +35k DTC library as an upgrade to my outdated OBD2 reader. This item presents with a full complement of features yet maintains an affordable price. For general diagnostics, I could find nothing not to like about this compact scan tool. A star was withheld for an unknown longevity factor - will update accordingly. In short based upon its initial performance, I do recommend this product.

Very nice code reader. Powers on instantly when plugged in to the OBD port. Lots of information available, more than I know what to do with. Can read and clear check engine codes, which is what I'm mostly interested in. The screen looks very nice, buttons are big and easy to use. Very good size, easy to hold on to while using. Very good value for the price, seems to be well made. Highly recommended.

This works, and if you don't want to use the phone and Bluetooth, it is an alternative. It is challenging to use, the readout information is extremely cryptic. I was unable to use it without a live internet connection to translate what it was telling me into actionable information. The lack of a touch screen is surprisingly disconcerting; it works ok, but you just have to get used to scrolling through all of the menus to get where you want. Not expensive, but would not be my choice for an OBD2 scanner.
