Have had them for years and absolutely love them. I even put them in the dishwasher top rack. They are guaranteed and you can return them for replacement if there is a problem. I have done that at Bed Bath and Beyond.

These are the only glasses we use. I wash them in the top rack of my dishwasher with no problems. The only issue they have is: Do not get any spray sunscreen on them. It will make them permanently cloudy. The company stands behind their product. We had a couple that leaked and they replaced them, no questions asked. That was several years ago and we haven't had any problems with them I like it that you can buy lids for the glasses.

I love Tervis cups. They hold up better than the cheap ones and they stand behind their guarantee. Through the years, I have mailed lots of them back and they replace them with no problem.

I have two tumblers still in use, given to us as a welcome to FL gift, in 1971. Have a set of 8, got in 1990. You can't beat them. Oh you can buy the cheap ones, but if they break, you'll have to buy new. Tervis you can replace, for us would be no big deal at 20 mile down the road.

They have all kinds, short, tall, handles and most any kind of logo you desire. They DO stand by their warranty but have never had a problem with any of ours. It's all we ever used poolside. Also, I put them in the dishwasher. I kind of laugh when I think about the 2 plastic thermo glasses that have lasted 44 years. Expensive, well guess not very if one considers how long they have lasted. Just good old made in America product.
