after read many post here.. i would like to test one of ur product.. how long i'll be wait for ur DIY car voltage stabilizer? mine is persona..

Hi Guys.. just COD-ed with eric yesterday 6pm.. No doubt he such a nice person and explained all about the VS and the grounding..

After installed it when i started engine i really cant hear the engine sound like usual!! This one of the instant effect that I noticed. Aircond become very cool till i have to set to the very min. The acceleration improved. Just press the pedal abit and walla! really smooth! Lamp also become brighter than before. My power steering also improved because previously it quite tight for normal power steering.

Very recommended seller and two thumbs up for him. next budget will install GC from him.
