Genial on a film such transform, pacific rim ... Can bring good feelings on certain games, provided you cut music (not because its output solely dedicated to Buttkicker) works well on Driveclub example (you can feel the road and imperfections) To fix on an office chair, or in my case, on my chair, it brings hardly reproducible subwoofers in a small room, even with a good subwoofer, and especially without disturbing the neighbors ... Too bad that the games have no dedicated audio output, hence the 4 stars but for the price, I do not regret. Seems solid, but beware the diameter of the "tube" to which you will attach the (chair leg etc), below about 2cm in diameter that does not, at least not without using a calle (it worked in my case ) because it takes the unit is very firmly fixed in order to transmit its vibrations (well it will not eject you from the chair, but enough is enough) Otherwise there are models for sofa (to put under a foot or fixing on board) but the price and the size is not the same ... Good "gadget" which we do not necessarily think, but can provide more (unless you have a subwoofer in a mega mega big room)
