Nice cup

I really like the cup except you have to pull very hard to get something out of it. When I looked at the top piece really well I saw why. There's something in there that stops it from a full flow. If you take your scissors and cut the top rubber piece just passed that point it works perfect.. if you look at it, you'll see what I'm talking about.

Great value and quality

This has an excellent seal, I can shake my drink up to mix it, and it doesn't make a mess. The straw is soft, although you do have to suck hard. I might make the opening a little larger but overall, I was really impressed for the price.

Not the best, but ok

It's ok for the price. The lid doesn't have a good ventilation hole so it's hard to suck through the straw. Spill proof straw is a neat feature. doesn't stay cold for as long as stated.
