Easy to install although vibrations seem to be to one side of the chair. May get another Buttkicker to even then out

Very good

I put this under the leg of a hardwood recliner. It makes the effect of deeper bass notes transfer into the chair without shaking the floor by about 70 to 80% effective. I adjust it via a separate Bass amplifier. I really enjoy the effect. Some songs are better than others, probably older studio filters or mixing errors before devices like this were around. I left the felt pads on the chairs legs so it could be brought back original later. I did have to take one felt pad off the leg with the ButtKicker mounting kit. The chairs legs bottoms were very large So I attached the rubber feet that are provided next to the old felt pads.

This is a very versatile mounting bracket that connects the transducer to the seats. You probably can't do it better than buttkicker designed it

It's a good thing I own a drill press or I would have had a difficult time fitting the bracket to my drum throne. It does not come with any holes pre-drilled and I also had to drill out the rivets holding the rubber feet on the bracket so I could mount it to my throne. Without a drill press it would be a daunting task to drill through the thick metal.
