It's been a fantastic addition to our games.
We keep it on the edge of the table, with the courtyard out of the play field (so if you're hugging the edge, then the tower itself can block LOS,m but we don;t have to worry about guys fighting in the courtyard while dice are being rolled)
It's really made rolling a lot easier and more fun, no chasing bouncing dice across the table or wondering where all the blue six siders have gone for my plasma gun. And the turn counter was a nice feature, no more asking "Wait, what turn is it?" or picking up the die we were using as a counter and accidentally rolling to hit with it.
Plus it makes a delightful sound when you chuck a fist full of dice into it ;-)
I gave mine a fairly good sized courtyard, fenced with the spiky fence bits...they come to really sharp points, so it discourages people from grabbing dice too quickly ;-) I may file the points down a little, I hand;t intended to line it with razor sharp fencing...
I should post some pics sometime.
