I bought ghese after returning another brand that I didn't like. These cups keep my water ice cold all day and fit perfectly in my car.

I order the 40oz hydraflow. These things are the bomb. I had put ice in mine on saturday morning and monday morning it still had ice.

Very durable have turned over full of liquid never leaked, also placed boiling broth in stays hot 8 hours.

Works as good as my husband's Yeti but I like the shape better as it holds more and fits into the cup holder of our car better. Love the handle too! My ice stays in it all day without melting, great product.

These are great. Although I don’t use the rubber tips to the straws. Too hard to get on but the cup and handle are great. Fits in car holder perfect! I’ve bought these twice now!

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.

I absolutely love these! 2 cups for far less than those super pricey name brands. These keep cold overnight! I have 2 sets now. One for me and one for my son, who kept taking mine. LoL!

Love these cups! They do not spill, I wish the bottom was just a smidge smaller as they don't fit very well in my car cup holder but I still love them!

The best tumbler, the best teacher tumbler! I left my tumbler in my classroom overnight and the next day the ice was still there when I returned. Worth every penny.

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.
