Bought a Pivot VS-E from this seller a week ago.
A fast responding seller. After I make the payment, the seller ship out the item in the same day. Really recommended seller.

After installed the VS a week, these are what i found.
- Faster throttle respond.
- Engine noise is smaller even in high RPM. (Maybe smoother)
- Radiator fan noise is smaller too. (I also don't know why)
- Lamp is brighter. Actually its look more white.
- The rest still cannot feel much different. But I’m satisfied with the product.
