I use them for a year, about 2 times a month.
They are very light, it is very important when making or even the roadie!
Practical and well designed, they are well padded and moletonnées inside with a cloth on the outside, stiff and strong, wide nylon handles. zippers are very robust and large seams are impeccable. Once rows like Russian dolls, and they do not flattened space in a closet. I recommend for regular use, like me, an amateur who wishes to protect the drumkit efficiently without having to store a rigid pyramid of boxes in his living room at other times.
Super value for money.
With the experience I do it again the same choice.
