This cup is really nice.The twist on cap makes it. I was using Tervis before I found this, and while I loved my Tervis when I first got it, after about a year the lid refused to seal the Tervis, and my ice would melt quick and if I knocked it over the water would spill out, so I started trying to find a better alternative. The reviews on this cup are stellar.I got the 32 Oz cup because I like a lot of ice in my water. It's a tall cup, so if cup size is important to you then get a smaller one, but for me, since ice is important, I got the 32oz.It comes with 2 lids. One sip type of lid for hot beverages and a screw on lid for cold. It comes with a long straw, and there's a push thru opening for the straw which grips the straw pretty tight, so it cannot fall out, and keeps the straw in place securely, and no air can get in around the straw, which keeps your beverage colder longer.I filled my cup with ice and water in the morning, and refill the water throughout the day and the ice NEVER melts! Not a bit! It's fantastic!!! Even if I leave it for a day, the ice is still there 24 hours later.Really great cup. I'll never use a Tervis again. This cup is far superior.Although it's a tall cup, I have no problem gripping it, and it fits perfectly into any cup holder because the bottom of this cup isn't wider than the top like Tervis' are.
