These coast very well. Our humid weather makes our glasses sweat like crazy, and we have to have coasters that are thirsty.

It is too hard for air to flow through these things. It makes the AC work too hard.

These coasters are amazing, they soak up the condensation from the glass very well.
would not buy any other kind

these coasters are so pretty, mind you not every one is really intricate... this is natural stone, some just have horizontal striations and no pretty swirl, but they do a better job by a little over their thirsty stones with a design (left more natural, so more absorbent?).  a coaster that absorbs is important to me, living in a humid and warm climate in summer.

They look nice, but cold drinks sweat and put rings on them.  The rings stain the coasters.  Sometimes they stick to the glass when lifted and then fall off and make a mess.  They work well for hot drinks.

You will need salt to keep these from sticking to your cup.  Surprises my company when they go to pick up their drink, the coaster sticks to it and falls on the table or their laps.

These stones work and look so much better than other coasters.  Only problem is that they can cling to the bottom of glasses when wet.  They definitely keep all the condensation off the furniture so I love them.

This is NOT a thirstystone coaster.  It does not soak up water, when I pick up my glass that has sweated water, there is a pool of water still on the coaster.

I live in a hot dry climate and these misting fans are spectacular at keeping us cool.

The two temps and humidity are different even when sitting next to each other!  But only by a couple of points,

I just moved to Hawaii and my SO told me we needed to order Tervis cups for the house, I thought it was silly because we have a full cabinet of cool pint glasses we've collect from our travels together. But then I caved and got this bad boy and I get it. I've been dealing with huge pools of condensation forming around my cups since i got here and god forbid I ever forgot to put a coaster down because all our surfaces are real wood. Not anymore! Turns out the Florida boy was right to say we should have these, in high humidity they're a saving grace. Plus the turtle is just super cute and helps me continually use the same cup.

I have this in Miami in summer. Its lens is reacting with sweat of your face. The stains remain. Also its design does not let air flow around your eyes so you sweat more.

I used this glass once - the moisture that collected on the outside of the glass due to condensation made the medallion fall off!!

These glasses do not stay fog free. But the larger issues is the fact that they get a sweat on them and it shades an odd double vision effect. I have never  had  safety glasses do this.

But they contain all the condensation and work as advertised, the glass doesn't stick to the coaster.  If only they had more color selection.
