Okay, so I finally got my hands on the OBDeleven NextGen scanner after reading mixed reviews. Here's my honest take after 2 weeks of use with my 2019 Audi A4:

First impression? The packaging feels premium. The device itself is tiny - like a USB stick with Bluetooth. Connected instantly to my Android phone (Galaxy S21). The app interface is clean but slightly overwhelming at first glance.

PROS:
- Scanned my car in under 30 seconds and pinpointed an intermittent parking sensor issue my mechanic couldn't find
- One-Click Apps are game changers (activated video-in-motion and disabled start/stop function)
- Works flawlessly with my neighbor's BMW 3 Series too

CONS:
- The subscription model stings (had to pay extra for battery adaptation)
- App can be laggy when loading detailed fault codes
- Confusing app versions (took me 3 tries to download the right one)

Final verdict? If you're a VAG/BMW owner who likes DIY tweaks, this is worth the investment despite the price. Just be ready for some in-app purchases. 4.5/5 stars from me!
