Flexi tube can't hold the weight of the filter and the threads are made of cheese.
on 20 May 2015
Although on first impressions it looks to be good quality, after fitting it to the microphone boom the flexi tube wouldn't hold the weight of the filter so it kept drooping down. Not a good start. So I detached it to try it in a different position and as I tightened it up the thread slipped and burred. Now the thing is useless as it won't tighten. Believe me, I didn't use much force at all. I'm an avionics engineer by trade so I understand about not over-tightening things!
I'm giving it two stars because the thread can be replaced with a new bolt and nuts (although this is going to be fiddly) and the filter itself does seem to be of quality. It's the entire attachment system that is at fault.
