Review
I bought this 4 years ago when volt stabiliser is an in-thing during that time, and the price wasn't too pricey. They volt stabilizer have quite a few features like prolonging battery life, improve ICE system, increase torque, response and power, and the last one that is very hard to believe, save fuel. I would say that this tiny purple box looks good inside the bonnet of my car, very cool looking with LED indicator too show my battery voltage, act as a gauge for me to see if it is time for me to change battery. Hard plastic, can last for very long. It seem to be a good investment after all. But the down side is the improvement that they state is very insignificant. So little that i don't feel any difference.

What I like
Cool looking and durable. Plug and play

What I do not like
No adrenaline rush. Insignificant improvement
