used it today, worked really well, used at the end of 50 foot, run 2 x 30 footers off it, one with wand and one with hydra force, presprayed 2 bedrooms while helper agitated then straight on to the wand, when helper finished agitation he sprayed landing and stairs while i was still wanding, just slowed the wand stroke down a little, other than that it worked perfect for both wanding and prespraying, so all in all, bluddy good piece of kit. and at 20 quid a ruddy bargain.
