Its tricky to find mind you, sat nav will take you to the wrong part of the estate.
Take the first exit off the roundabout in frontof the estate, then take the first Proper left (there is a big white sign with blue writingon it) Keep going and you will see a sign on the rhs listing all the companieson the estate including kaizers but don't go down that road, keep going and turn next right and he's down there.
