Pearl Air Suspension Feet - Replacement Accessory for Floor Tom Legs

"The R-40/3 are air suspension feet for Floor Tom legs. These Air Suspension Rubber Tips allow your floor tom to rest on a cushion of air. These large rubber feet prevent premature sound decay from floor contact. Floor toms never had it so good."
Does this product work the way Pearl claims? Here's the results for my very specific use case.

Yes they work very well

I throw 2-3 little cotton balls in my floor tom... almost completely cuts the sympathetic tones out without killing the sustain on my floor tom.

I ended up doing the same.

You should try wrapping the legs with sound deadening material, like the same stuff in cars, so the metal legs transfer less vibration. For science, maybe. 🤷🏻‍♂️

Ended up putting cotton balls inside the drum.

[@drumur]

Ironically you guys are talking about deadening the times when these do the total opposite

[@COBRAHAWKband]

You are definitely right in that these increase the sustain of the drum, but the goal for me was to create some isolation between the floor tom and the vibrations created by the kick drum. I have added some cotton balls inside the drum and some tape to the reso head to combat the added resonance.
