i am EDGE (BT302 + booster) user, since a year ago.
My ride is Hyundai Getz 1.4A which is quite heavy and underpowered :sad:
I found this VS in Cari chinese forum which is very hot discussed since last year. Few of my friends from Getz owner club in Cari also highly recommended the EDGE VS to me.
So, i just give it a try due to the creator has agreed that to refund within 2 weeks (i guess, can't remember how long) if i cannot feel any improvement.
(before use EDGE i did tried on the 70,000uf VS, it was so...hmm...not really good, just a week i quickly return to the seller)
The EDGE has to run in to get optimum performance, to me is quite special feature.
After 2 weeks, i feel very satisfied with it although it's still not hitting 100 hours.
My ride - the heavy Getz become lighter, smoother, more responsive, and i can easily rev up RPM with more power. The feeling is complicated, it's just like the car has revive from death

I do also noticed a little improvement on fuel saving. Before i install EDGE VS, normally i get 330KM with full tank

now i can constantly hit 350-370km, although not much but i feel very happy.
we never know how good it is until we try. i'm glad that i make a right choice.
Now, i'm planning to get another EDGE VS for my new ride - Kia Forte
