Spill Stoppers?

[MarkEastover]

Has anyone tried the Spill Stoppers advertised on QVC for boiling wort? Looks too good to be true!

I just spray,but this should work.

I have no idea what a spill stopper is but I can wholeheartedly recommend Fermcap-S for stopping boil-overs.

It's apparently a silicone lid with some interesting geometric characteristics inside.

I should get one of these for my wife's favorite rice pot. Not a batch gets made without a boil-over
On a boil kettle? Nah...
