One important difference is how the shaker is powered. Pinshakers utilizes it’s own power supply that turns on and off with the game so you aren’t stressing your boards. Not sure how pinsound shaker is powered, but I don’t see any external power supply included with their kit so I assume it’s powered off one of the boards.

I can also say the quality of the shake is very good, a low rumble, not like you feel with some newer stern shakers, which vibrate the hell out of the game. The intensity of the shake is also controllable with a dial.

You can have up to 8 triggers at one time and 16 total comprised of solenoids and flashers, which I think is plenty. I only utilized three triggers on my wh20 and tspp and felt that was enough. Installation is simple, plug and play, and customer support is top notch. Install shouldn’t take more than 30 mins.

We are a distributor for Pinshakers. I was so impressed with the capability, easy of use and install, I wanted to help get these out to people. So nice to have a shaker option for wpc games as well as whitestar and system 11. Shipping is fast via usps priority so we can get it to people in 2-3 days.
