Also what I found is, that the screw plate has been screwed too hard to the stock, making the stock bent a little bit in the middle. Doesn't seem to effect bristle length though.
Also, you can see where they used the staples in the the top corner, and lower corner. Little bumps coming out, I only realised they were staples because the metal of one of the staples started to show. That's purely cosmetic though.

Excellent brush though, works very well on glass.
There were one or two instances today, that I would have preferred my stiffer Ionics multipole brush, one window had rosepetals dried on it, and they were very difficult to shift, I don't think I would have had that problem with the Ionics as much. I'm absolutely not saying that the brush needs to be stiffer, just that for very dirty frame cleans, a slightly stiffer brush could be better, also I had one window were there was some yellow/orange muck on there, like from a bee or something, that didn't come off. Then again now that I've used this brush, I really would not like to go back to the Ionics, it's too stiff, doesn't splay nicely. It's remarkably similar in bristle spacing, and the amount of brisltes per hole, even the bristles seem the same, just a different grade. I'm quite happy about that.
But that would probably only be for 10% of cases, I mean, a brush that can clean this well for 90% of all things you need, including being a real superlite brush, is marvellous, and a very good thing.
I hope in time I can upgrade my brush to an improved model with more bristles, and perhaps even lighter, but that might be difficult.
Alex, is there plastic available in a honeycomb or similar structure? Because I can see that being the only way to cut down the weight, there is almost not stock anyway.
Am I happy with the brush? Heck yea, for me it's absolutely in first place, never used the Tucker.
