Has anyone tried these? They’re shaped like coffee beans but I’m sure they would work equally well with tea.
I have not specifically tries these, but I have used something similar. It did keep the tea warmer for longer, but not substantially. You would be better off to put it in a good travel mug with a lid.
It’s been awhile since this thread was started. Anyone get a chance to try these? They sure are pricey, but if they do what they say, I’d buy ’em.
I found a pretty good review about them on google. The guy got a set from the kickstarter and then did some testing in his home.
Thanks so much for the link. That guy was pretty darn thorough. I’m bummed about the result tho. Oh well!
