BPA-Free 20 Ounces Acrylic Tumbler with Straw, Double Wall, Smoke

These cups are great for my smoothies, which I make every morning and drink on my commute into work. They keep the smoothie cold, my hand not, and are the perfect size for my 1 c. liquid, 1.5 c. frozen fruit + banana smoothie.The seeds of the fruit inevitably get stuck in the straw, making some sort of brush-type cleaner essential. (I bought the  Brushtech Sports Bottle Straw Washing Brush B23C  and it does the trick just fine.)Given that I use these cups every day I feel like they have to go into the dishwasher to get properly sanitized at least once or twice a week. They're too tall to go on the top rack, so I usually put the cup on the bottom and the lid on top. I have yet to have a problem. The straw, however, is a different story. I've melted numerous straws in the silverware basket, so I now keep a supply of spares on hand. They seem to do fine on the top rack, but I don't like that the dishwashing water can't spray into them up there, so occasionally I'm wild and crazy and gamble with them on the bottom. Sometimes I win, sometimes I pull out one of my spares and display the old one as artwork.

Good, double walled. I filled it with water from the tap,,,luke warm, then put in the fridge. Several hours later it was still luke warm. I realized that the insulated walls actually kept the drink warm, so I know that works. Picture here looks dark. The one they send me was pretty much clear. I don't blame the cup, just the description or person who shipped it. Also, the straw will not fall out when put through the cap.

This is the second tumbler of this type I've used. The first one is a Cool Gear product that I bought at Wal-Mart. It's still in great shape, but it has a Christmas pattern on it, so I decided to find a neutral one.I've had this tumbler less than a week, and through gentle use (It travels from my kitchen to the desk in my study--I rinse it out, refill it, empty it, and repeat) it has already gotten a crack in the outer wall of the tumbler, and the straw broke when I dropped it in the sink while rinsing the tumbler. It is entirely too fragile; I'm very disappointed and won't be replacing it with this version.

I was looking for a Tumbler to have at work with me. After searching a while I ordered this one. I wish I had kept searching. When I got the package it was torn, crushed, and had a big hole in the side. When I opened it I found that the straw had been snapped in two. After getting a replacement straw I took it to work with me. After a few shifts I accidently knocked it off a table and it hit the ground shattering into many pieces. If you need a cheap tumbler go with this one. If you want something worth your money and is durable, keep searching.

Loved these at first, took them everywhere. Biggest downside is if you drop them accidentally (I've dropped two now) and both broke immediately (the inside/outside components separated).

I loved this cup but as I started washing it, condensation built up inside the walls of the cup.

Bought this cup to use while at work. We have a water cooler but my work uses small 4 oz cups so I bought this to use instead. Works as expected.

Works great with Keurig tea by adding ice cubes and brewing to create an iced tea. Not too shabby and a good selection of colors.
