My title says it all - I LOVE tervis! These can go in the dishwasher, the microwave, or even the freezer.  They are nearly impossible to break and they don't leak! They keep my furniture safe bc they won't leave water rings, and if you get the lids they are almost spill-proof, too!  I've had other cheaper brands that have broken, cracked, or filled with condensation from the dishwasher. None of those issues with the Tervis.  I love these and want more!
