They hold ice for a long time. But they do not fit in your car cup holder. Plus, mine arrived slightly dented on the bottom so they rock a bit when you set them down.

I was thrilled to find a replacement for my previous Hydraflow 40-ounce tumbler! I appreciate the quality of the tumbler and rave about it to my friends.

Good, but you need remove the strobe if you want use drinks directly from the cup, because if don’t remove you can hit your eyes, specially if is used for a kids.

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.

This is a great set, and the colors are really nice. I got the yellow/blue and yellow color set. Keeps things cold so long! It's a little too big for my car cupholder, but I am very happy with it.

Not real excited about the straw as it has a rubber tip that’s not appetizing at all! As for the cup itself, it fits in the car holder and I love the handle on it! Keeps drinks cold for several hours.

I love these cups! They keep ice for 2 days! Very durable they are made better than any other stainless steel cups I will definitely order more of them

Very nice! The only problem is they are to big and do not fit in my car cup holders😔 Other than that they are wonderful. Also like that they are dishwasher safe.

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!

These cups are amazing! Love that they hold 40 oz and have the built in handle makes them so easy to drink from in the car. Highly recommend. Please bring some back- need more colors!
