Pretty good cup

I bought this to use specifically on my riding mower. it's just a tiny bit too big to fit in the drink holder all the way down but if you push hard enough, it'll get wedged in there and stay. I like the way the rubber in the lid fits around the straw and doesn't let dirt and grass get inside the cup. Keeps ice pretty good out in the sun most of the day. For the most part I'm happy with this cup and would recommend it. Very reasonable price also.

I purchased for my husband. He absolutely loves it! It keeps his drink cold for hours with ice still in there. Very happy with my purchase and would definitely buy again.

Great cup!

Great cup! My husband prefers not to drink from a straw and although this cup comes with one, it also has the slide that you can open and sip from. So now I get his straws and he still has a cup he loves! We've since bought another! It also fits good in our vehicles cup holder which is on the larger side.
