I didn't even think for a second and from the first time I used them I found the utility of this product. For less than 70 euros you can have a complete set of bags that are very good for packing up your drum set, move it to another studio and bring it back. Same for local touring (where no plane trips are included) and for every situation where you need to unmount your drum kit, move it, play somewhere else and return it.
Much faster to do everything than the plastic hard cases and of course they need less space. You'll be amazed how comfortable they are. First time I've used them to move my drum set, as most people have hard cases, almost everyone in the studio told me how awesome it was to see that with a normal drum bag set you can move your drums easy, fast and with almost no effort at all. I highly recommend them.
