I like these cups and they are great quality, however they do not fit in a standard car cup holder. I bought them to take with me to work, errands etc a But I cannot use them.

Love mine so much that I bought them for gifts for my Bible Study group this year as we launched our be healthy goals. DRINK MORE WATER! PROS: Keeps ice for 24 hours - in the house/car, assume less when it gets hot outside. Fits in car cupholder. Love colors. CONS: Silicon straw cracks/tears in the middle. Hard to find a replacement because it has to be so long to get to bottom of cup.

I have the floral/teal ones. The seal is great. My only complaint is the center stopper around the straw comes loose. I left mine in the car in a parking garage in over 100° temps in the car and still had ice in it at the end of the day. Will use them at the beach, too!

Beautiful well insulated drink tumbler will keep your beverages cold for hours. My only negative is that the lid can be fragile. One of my lids arrived broken even though they were well packaged. Sam's club quickly replaced and they have been excellent for use. I really like the SS straws with the silicone tips.

I got several of these, 4 pairs for Christmas presents (and all the recipients loved them!) and another 2 pairs for myself. Albeit large, it fits in car cup holder and handle makes it convenient to carry. Attractive colors and design combinations at such decent price! Happy with this purchase.

I love these cup. I bought the 1st set came while my sister in-law was visiting, she too one home with her. I took my cup to work with me and a couple of my coworkers really like it, so I ordered a second set and gave it as Christmas gifts. I love the size and that it fits in my car cup holders. They look really nice and keep my water cold.

These tumblers are great. 1) they have a locking mechanism so the straw doesn't fall out, 2) they are dishwasher safe, 3) they have a straw for cold drinks and a lid for hot drinks, and 4) they are the largest tumbles I have found that fit in car cup holders.

I wanted a larger tumbler than my old one and this is definitely big! It keeps ice frozen overnight, easy to carry and nice color. I like that there's a solid color and a printed one. I don't use the straw or rubber squeeze option so I can't speak on how easy it is to use or clean.

The 40 ounce Hyrdaflow mugs are great. It keeps my water cold for hours all night/day. Plus the mug does not sweat on the outside. I have not tried it for hot liquids. But it is suppose to keep things hot too. They sturdy handle is convenient to carry the mug. It is taller than most mugs and it fit in my car's cup holder. However, it will not fit inside my husband sport's car cup holder. I love the mug I have ordered several of them for friends.

Bought these cups for a road trip and we were SHOCKED with how long ice lasted. We filled our glasses with ice at lunch and still had same ice throughout the entire next day. Bought another set in different colors and a set for my parents. Highly recommended!
