Simple idea well executed. I use it with my Monotribe and Volcas. A passive mixer where you have to adjust the volumes through the various connected devices. Small loss in volume for each connected unit, but portable and no batteries required.
Well thought out gameplay that can provide a quick skirmish, but with the depth for really interesting strategic games. One set is ok but 2 sets really do open up opportunities. The extra ships, although not cheap, are really good and add great depth. A really good purchase.
