Yet to play a good game without them.

I think its a bit like a pizza without toppings!

From simple games through to complex games, if anything just gives you a second to rest your hands or wipe sweat off.

Unfortunately many times they are not rebuilt properly (or even removed when completely when I mean fully stripping the playfield) so they are sloppy, have broken yokes, broken ring/rod assemblies etc.

When done properly and they are adjusted correctly, makes all the difference.
