For the price was a good solution to round out the sound

For those that don't want to spend a couple of hours fine tuning their toms, this is a good solution

I thought this control rings were the perfect solution for cutting off harmonics and giving the drum a quieter and controlled sound, And they do, but the thing I didn't have in mind was that they don't stick to the drum head but rather just sit on it, so in my bigger toms they rattle every time I hit the drum and it is clearly listenable.
