Millenium Sound Control Ring Set Std

I use them along with the Millenium drum heads set and it works great.

It removes all the bad harmonics and make drums sound much cleaner.

It is cheaper than all the other options for sound control, but still works almost as good as the expensive products.

With moongels and similar products you have more freedom for placement and control of a sound, but for this amount of money, this is a killer deal.

A bargain compared to other brands, pricetag is adeqvate for the level of sonic impact you'll get. I must say the fitting/sizes could be better overall. Some rough edges and will leave a tiny space inside the rim. But if you can live with that, there is no reason to buy any of the more expensive products in my opinion.
I cannot answer for long term durability, only had my set for a month or so. Overall recomendation: try'em. =)

The rings quality is pretty good.

I personally don't like to use them. They make a plasticky vibrating sound i can hear through the mics.

I don't think there is any wrong with the rings, just a matter of taste or maybe tuning range i use.
