I found some reviewers were surprized that they did indeed work!
I can confirm that they do I in fact make a huge difference and I was surprised.
Now don't go expecting your neighbours to not hear or feel your subs at referance levels. The do in fact reduce vibrations but not stop them. You need to be realistic in your expectations here! They did stop my closet doors vibrating at normal levels but my normal may differ from yours.
Give them a try, you may be surprized as I was!
