Much better performance than I expected. Installed this on a 3 seat couch, used just the iso feet and the buttkicker under one leg. It kicks much harder than expected, and all the included pcs worked out of the box. I like how extra iso feet were included just in case you have a larger couch.

The buttkicker advance is capable of some very subtle effects similar to how the PS5 controller haptics work. It required very little setup from me, I thought I was going to have to time align it, set a low pass filter to blend with my subwoofers.... I didn't have to do any of that, I just the intensity to where I want it and leave it alone. I especially like that the amp wakes up when sent an LFE channel and doesn't require me to get up and turn it on, this feature is not advertised but was a nice surprise.

I like the effect to be rather subtle for films, I keep the intensity around 20 and use movie mode to filter the output. In video games, I set it to game mode and run it nearly flat out at 40 or 45 on the intensity dial. The haptic feedback for this like gunshots in FPS games is very immersive.

2 things that keep this from being 5 stars:

1) The included screws are extremely soft and I stripped 2 of them putting the iso feet on, go grab some real wood screws to avoid this.

2) The included amp has no way to dim or turn the front panel off and it is extremely bright. Also the intensity scale is 0-50 rather than 0-100 which seems like a weird choice to me, not a dealbreaker…
