LF shakers - anybody tried?

[AlmaataKZ]

I recently bumped into low-frequency transducers like this one. http://www.thebuttkicker.com/home_theater/products/bk_lfe_kit.htm

Does anybody have them or maybe tried them in a showroom or smth? What is the effect like? would it add some subtle deep tactile sensation from bass at low volume or is it a vibrating gimmick?

I'm sure the WHF test team are agog!

We have tried some in the past, and were less than convinced.

These sort of things are used on stage for drummers when bands use in-ear monitors. It allows the drummer to feel the kick drum better. They are attached to the drum stool or "throne" depending on how famous you are
