Can be used to mitigate short micro breath caused by wind but will not do more than windmuff or anti-pop decent quality foam. The fiber hair (?) Stand out much more quickly than other brand Deadcats. Received this morning as soon I filled the room mics fiber ... On a shotgun correct size this Boya DeadCat remain short and it will go to the next model that seems too him. A small problem size for these products is primarily for micro shotgun type RODE Video Pro or NTG1 / NTG2 and also to the many micro more economical.
Basically, it DeadCat can do the trick by following the philosophy of "It's that or nothing", but I would recommend strongly to put thirty euros for Deadcat Rode.
