There is something about the Mk1, I like it better than the Mk2.
I tried something new today, first of all by accident and then I tried it on a few windows.
I forgot to fasten one of my clamps and the brush started to swivel on the window, I had to lock my gaz brush because I had two things swivelling, once I locked my Gaz brush and tried it, I was amazed by the action, but it would take some getting used too.
