Well, since there already reviews on this product are - if these are not fake reviews - I seem to be an exception. The knurled screw to screw has a well-incompatible thread to my EOS 600D - and other accessories, to which I then tried the screw. Thus, I do not know how the handle as in everyday life is, I can not fix it. I then sent him back - with a simple, appropriate replacement screw would have done it. Again I do not try to order as I suspect, the next would not fit.
