just purchased this eco concept vs with the hks grounding cable. Really good service provided and recommended seller. Not sure if it is in my mind but my Proton Saga BLM manual feels alot smoother to drive otw back from cheras and maybe the radio sounded abit louder than usual . Other than that not so sure yet... my lights seem normal and frequency on fly.fm is clear but hitz is still giving me rather shitty reception !

Overall, I'm very satisfied with the service and the item and will definitely recommend this product for this price.

Thanks bro!
