These are great cups , handles make it easy to use , have options of using the straws or not and has seals ,to close the lid up , fits in cup holder .

These seal nicely and stay cold as advertised, but the lids are fragile; the hinge a tiny nub that breaks easily. Also, the silicone sleeves for the straws are brittle and taste funny.

These cups kept all of our drinks nice and cold on vacation! I like being able to have the drink spout and the straw. They are durable, easy to use and a great value.

Got these for grandson for Christmas he loves them, his sister liked the also, he gave her one. I bought two sets and keeping one Hydraflow and probably give one for a present, great buy/price and size is great.

These tumblers are great. They keep my tea colder than any tumbler I have ever had. I also love that they have a handle. I would definitely recommend to others.

I was so pleased after purchasing these for myself that I ended up ordering more for Christmas gifts. I love the large capacity, the handle, and the multiple methods of drinking from them.

Is there absolutely wonderful They keep the drinks cold for over 24 hours. This is the second set I have bought, and this one was a gift for a friend who used one at my house and just love them.

These are the best tumblers I ever had. Sturdy, tight fitting lids. The cunstruction is high quality. The straw goes all the way to bottom, plus 2 extra straws with rubber tips come in the box!

I bought my mom a set of these cups for her birthday and she loved them so i bought myself some for my birthday. I love that it's 40 ounces because it helps with drinking water and keeping it cool for me.

I leave work at 4:30pm and come back at 7:30am and the ice has not melted. Love these cups and the fact that they hold 40oz. I drink a lot of water.
