I must say when i first got the new improved brush i thought i`d been sent the original again without inspecting it properly,the brush is slightly shorter in length and the tufts of bristles are in different places though retaining the same amount throughout the brush itself.The bristle length is 3mm shorter which when looking is hardly noticable but is radically noticed when in use,IMO this brush is the best i`ve ever used as it works well on all types of windows ie leads small panes and plate glass,there is no bumping over the glass on leads at all and the brush now stays in line on the window when in use and by this i mean it goes where you want it to go.The new version dosen`t push flat on the glass which is what i hate it has the perfect tension on the window with the ideal splay,it also splays up nicely under sash windows and the like and glides accross the window exactly how you would want it to,the main and most important thing for me is that rinsing on is easy with this brush allowing you to work quicker.The only thing i`d like to see is the gap round the jets with more bristles,i feel it`s a waste of space and would only enhance the brush even more.So there you go i think THE brush is now available to buy at last and it`s been a long time coming,well done Alex it just goes to show you the difference between a product that`s designed by someone that uses it daily and someone that dosen`t,i`d like to see me get a discount aswell seen as i have 2 of the original versions which i can`t get on with lol.
