It's not on their website yet. Lovely brush, beats the one you lot go on about by xline. I had one by xline and I reduced the weight down a lot with an electric grinder and sander. xlines brush is really good but varitech's newest range beats all the rest for lightness and scrubbing power with 2-6 easily removable pencil jets or fans, stocks are as narrow as the extreme but with many more bristles mono filament and more compact so they don't fall out. Really good for removing green fly on glass.
