Simple Green Solutions - Acrylic Double Wall Reusable Cups with Lids and Straws for Cold Drinks, Insulated Plastic Tumblers with Lids and Straw, 20 oz Capacity, Clear

These have great functionality but they are very fragile. We got the package and one of the lids was cracked. And I had one fall on the ground and the plastic shattered like glass

These are perfect. They are just the right size. They are easy to hold, easy to fill with ice and/or a beverage, easy to clean, dishwasher safe and sturdy. These tumblers are great indoors or outside. I've ordered two, and I will order more today.

Keeps drinks cold and need to use clear cups at work

I use these for iced coffee in the mornings, and love the size and overall look of them. They hold ice well, for at least the length of time I need it to finish my coffee, and don’t get slippery with condensation. I only gave 4-star because I love the cups, but even hand washing, they only last about 3 months before the inner seal wears off and water or coffee leak in between the layers. I’ve had to purchase these cups a couple times, and am now probably just going to move on to another kind.

I would avoid this product. This is my second time buying this item. The same problem occurred with both my first and second purchase. The poor manufacturing allows the seams, either around the top rim and/or the base which protects the vacuum-formed double-walling, to easily crack or split such that, when the tumbler holds cold drinks, condensation forms in between the double-walls that won't evaporate or go away (unless you cease using the tumbler for about a week) causing an ugly, scuzzy-looking tumbler. By the way, for both my purchases, the tumblers were neither dropped nor placed in the dishwasher. The splitting of the seams occurred during careful hand-washing. The quality of the acrylic is very good. But the splitting that ruins the vacuum-formed double-walling makes having this item pointless.

Simple useful cups to help with drinking more water.

Like other reviewers mentioned, the inner cup broke and separated from the outer sleeve after a few months use. So I guess if you want one of these, plan on buying a few a year becasue they don't last long. It's too bad because it was a decent water cup for work and kept ice cold enough for a few hours. I just can't recommend it based on the cheap build quality.

Bigger than what I expected but when my last lid broke I had to replace it and that's when I found this one... I wished the straw changed colors like the last one I had but it's okay I like it anyway
