So since this group is all about Tools for DMs, how about an opinion
on the magnetic "condition" markers from Alea Tools?

They seem like a neat idea. But being magnets, my concerns is they
might try to latch on to each other when put close together. And
apparently this is a problem some people do have. Still, the ability
to quickly and easily evaluate the battle just by glancing at colored
discs seems highly useful. Anyone here use them or have any opinions?
