Tecbuk dual trim red polyester monofilament With scraper and scrubber pad.. Recieved the brush on Tuesday, was instantly amazed how well the brush is put together, it shows quality and looks like it will last. When I first opened it, I thought it looked very small. I compared to my dual trim super lite, and the stock is an inch or so shorter, but the bristle coverage is pretty much the same just the edges are rounded rather than the superlites squared.. The bristles are thinner and look like there is a lot more. There isn't a huge difference in length between the dual trim and it splays a lot better and easier. The brush seems to glide over the glass great, also on leaded glass. I found sometimes my super lite would stick and jerk on the glass, but the tecbuk just flies over and you can feel it in your fingers that's it's still giving a good clean effortlessly.. I am very pleased with this brush and it puts my other 4 brushes to shame. Some will disagree and others will say its a sales gimmick, but I bet Richard is laughing behind his computer as some of the insults. I too myself made a few negative comments before about this brush and I take them all back! Richard isn't given enough credit for his brushes and for those to comment when they haven't tried are just wrong! I defintily feel the brush was cleaning quicker... Price wise, well it's worth every penny. Really it's only a couple of quid more than others but you can clearly tell why it's a few quid extra. But when you need to re new, you only have to buy the brush head, everything else can used again. Think Iv covered most things, Iv only used it for 7 houses but I am a very happy chappy and will be ordering another very soon along with a boars hair. 1 last thing, customer services is second to none! Cheers for all the help and info Richard.. For those who have thought about it, don't think to long!! I'm sorry i didn't buy one ages ago!!
