I bought Snareweight M80 magn. Overtone Damper Wh. for an 16" floor tom, to reduce the overtones that I couldn't get rid of with moongel. It's much more elegant than moongel (that's my opinion)
The product is very easy to assemble and well finished (it is made of leather).
From the first tests I was very pleasantly impressed by the reduction of overtones and the floor tom sound.
I recommend this product.
