"The mechanic quoted me $700 for a potential fuel system overhaul. Turns out the issue was a simple fuel filter blockage."

"This app and device combo is a lifesaver. It allows me to diagnose issues quickly and even provides me with the recommended parts needed for repair."

"I bought this to check a used car for my daughter. Thanks to BLCKTEC, we found hidden issues and avoided a bad deal!"

Works perfectly on my 1997 4runner. Thank god for this, half the price of the one at my local parts store and no bloatware. Just an app that works. They don’t try to sell you a premium service to access the device you just bought.
Affordable and efficient. I am thoroughly impressed with this bluetooth car code reader. Its ease of use and feature-rich app make it a standout tool.
Awesome scanner, great value! This scanner did wonders for me. I was a bit iffy about getting a scanner that works thru Bluetooth, as pairing can be a bit tricky for bluetooth scanners. But this one was a breeze to pair.
Excellent device for diagnosing vehicle problems. It's so convenient compared to other OBD II readers that only give you codes that then must be referenced in a book.
User-friendly and comprehensive. This bluetooth vehicle scanner has been a breath of fresh air. Instructions were clear and easy to follow. The free app was a pleasant surprise, offering extensive features at no additional cost.
Well worth the purchase. This device is great. Very easy to use, very detailed in info given and gives the option to find a repair shop.

The 430 reads the car. The app tells you what to do about it.
Lifetime app access comes with this bundle. No monthly fee, no premium tier to unlock later.

Plug it in once. Scan from your phone.
The 430 pairs with the free app over Bluetooth, so the report lands on your phone in seconds.
