In terms of function, there is not much to say, he just kills Pops. This makes it good, an improvement is clearly perceptible. Point deduction, there are, however, for the rather poor quality of the whole structure, because this is incredibly unstable. The clamp for mounting on the tripod is not very grippy and the pop screen falls down easily. You can apply as firmly as you want, apparently the screw separates from itself. Furthermore, the rod very flexible and unstable, so the pop screen constantly loses its position and must be re-attached. In addition, the pop screen itself at the upper end of the bar is pretty loose and must be tightened again.
A total of three stars, because the function is given in principle, but that is all connected to a lot of fumbling. For longer recording sessions uninterrupted operation is not possible, which is a bit annoying over time. Apparently it has well but his reasons why there is (much) more expensive Popkiller. For the price, I can still recommend buying.
