vLinker MC+ (BT3.0/BLE4.0) OBD2 Scanner Code Reader Diagnostic Scan Tool for Android & iOS & Windows, Black

This product is very easy to use. Using it with j scan software app. Bought it to change the tire size on my 2012 Jeep Wrangler JK. Application was simple with a quick Google on how to do it only took me a few minutes change tire size of my Jeep. I went from a significantly larger tire to a smaller one. Adjusting the tire sizes dramatically improved the operation of the Jeep. I am looking forward to using more of the functionality on my Jeep as well as on other vehicles. Did have to pay for a three vehicle license from jscan but all in all very worth the value!

Works great with the Jscan app and the Car Scanner ELM OBD2 app. Setup was clear and easy and I haven't had any connectivity issues. I've used it successfully on a JL Wrangler and an early aughts Honda CRV so far. OBD2 is extremely complex and unintuitive, but that's an OBD2 issue, not an issue with this product. Zero issues so far.

Tested this OBD2 scanner on both iOS (iPhone 15) and Windows 11 platforms. The dual-mode BT3.0 and BLE4.0 is the main selling point here, offering flexible connectivity. BT3.0 pairing was fast, stable, and compatible with Torque Pro and Car Scanner apps without issues. Critique: • BLE4.0 Mode: Exhibited noticeable latency when reading live data PIDs during acceleration tests. This delay makes it unsuitable for performance tuning or high-speed diagnostics. • Build Quality: The plastic casing feels cheap and lacks the tactile durability I expect from diagnostic tools that might live in a glove box or tool bag. • Firmware/Software: No bundled app provided, requiring third-party apps and manual pairing, which might intimidate less experienced users. Conclusion: Good entry-level scanner for casual vehicle owners or hobbyists wanting to clear codes or check basic data, but not suitable for professional or demanding diagnostic tasks.

Worked well and seem to be a great value compared to other options to correct the speedometer.

It connect to every car but everything is all about the program mostly.This device transfers any kind of data from car ECU to your Diagnostic program. it's very cheap, connects quicky to most of the cars, sometimes struggling with japanese cars. It's also easy to use, just connect to it via Wi-Fi or Bluetooth and open the program

I purchased to use for ios with alfaobd app but did not work and kept telling it was not compatible. With android connected just fine with no issues and was able to use alfaobd app with no issues.

Works great on my Jeep JL

Works great and connected quickly to my device. It was compatible with J Scan for my Jeep Grand Cherokee.
