I just got some of the Moon Gel things after hearing so much about them. I usually do not muffle drums at all, but I've been doing some small jazz venues and a bit of dampening would be nice. One little square of the this stuff will dampen the drum enough without killing the playability of the drum like rings. (btw, if you ever want to make 'rings' of your own, take a razor to an old drum head before you get rid of it, it's mylar, fits the drums, and you don't have to pay for it) Of course the effect of the moongel depends on the heads as well. I noticed comparing the effects on EC2s compared with G1s. Moon Gel plus 'dampened' heads equals a pretty dead sound unless the drum is 16" or bigger. However on my other kit with g2s/g1s with 13,16,18 toms it works nicely. (It's great for when I use my 18" tom as a bass) It's great because you can just take them off, move them around, etc. for different songs. Unlike rings they last longer, rings can get crumpled or whatnot, these things just are gooey little squares. Wash them with soap and water, dry them and they are sticky and ready to go again like new (that is if they collect enough dust to stop being sticky) These also work for other stuff like cowbells, blocks, or other things you may need a controlled sound for
