We live in Queenborough, and got connected in December 2011. Initially vFast didn't think we would get line-of-sight from Ridham due to the Sheppey Crossing, but we were lucky.
The receiver unit is very small, and installation was simple. Performance is fine for what we require, and vFast customer service is amazing. If you are used to BT or Virgin, vFast are streets ahead.
Highly recommended, but remember line-of-sight only
