I used to transport my snare drum folded into a blanket, placed in a shopping bag. As for my bass drum and toms - no bag whatsoever, just a blanket on them in the trunk, to keep from grinding on each other too much.
Then I got these bags and, of course, it's a big step up. The drums are a lot easier to carry, they're protected much better, the whole transporting operation just looks much much neater.
However, this is a budget buy - the bags are not super high-quality. Had problems with the bass drum bag zipper from the get-go - it tends to get stuck easily. The inner layer of the bass drum bag got torn on the lugs pretty fast just from jimmying the bass drum in in a normal way, and now its a pain to get it in, because the lugs keep getting stuck in the holes. There is also not much protection - the drum bags are quite thin, so I would recommend these only for transportation in a car - not a gear filled van, not by any means an airplane.
Otherwise - good for the price!
