Corkcicle Tumbler - Waterman Collection - Triple Insulated Stainless Steel Travel Mug, Waterman Seafoam, 16 oz

I had the smaller cup that I used for iced drinks in the summer. Kept drinks cold for hours. I wanted the big one for coffee, but was disappointed that it doesn't keep hot drinks got it even warm for more than two to three hours. Also the top is a little different and doesn't stay open to drink. I guess I now have a bigger summer cold cup.

This was the first I bought (I own three). I love it so much. I use it at work. I was constantly back and forth pouring out my melted ice from my old plastic cup and refilling it all day. I read the reviews on this and bought it. It was a great purchase. I fill up my cup with ice in the morning and then only have to add water the rest of the day. It keeps my ice frozen and the water cold all day. I've even walked out leaving it on the desk and when I came into work the next day some of the ice was still frozen and the water was still ice cold.I've already gifted one of these and plan to gift a few more. Not only is it great at keeping things ice cold but it is stylish too. That part was important for me as I carry it around with me to meetings all day. I don't know about its ability to keep things warm although it is obviously well insulated. But I have only used it to keep my drinks cold so far.

The tumblr itself is fine and I love the finish of the Waterman. That being said, I bought the "Grey" color, which is pictured on Amazon as a pretty deep gray, much closer to black than it is to white. That bears no resemblance to what arrived. It's a pretty light grey. I happen to like the color of the actual item as well so I will keep, but it seems odd that the color is so dramatically different than pictured. Reading some reviews here, I seem to be far from the only person experiencing this!

This is my second Corkcicle and I bought this one to keep smoothies cold. (I also love my Waterman Canteen). I typically make them around 6 AM and have it for lunch around 12 or 12:30 and the smoothie is still as cold/frozen as it was when I made it 6 hours before. If I could give this 10 stars, I would. I highly recommend Corckcicle over all of the other brands. I have a Hydroflask that has leaked from day one and doesn't keep liquids cold nearly as long as Corkcicle!

Good Quality cup but I'm really disappointed in how off the coloring is. Would like to order multiple colors, you know to match outfits :) but the coloring on this first order was so off I'm not sure I will. Otherwise it works as described, decent cup.

1. Many people have commented about the rubber ring on the lid not staying in place and not sealing properly. When my cup arrived, the rubber seal was twisted and not set properly in the groove of the lid. Once I figured out how it was supposed to go, I was able to correct the problem, and I have not had any issues with the seal or with it staying in place, even after several uses. The manufacturer really should make sure that it goes out the door in the proper place.2. I was very disappointed in the ability of this cup to keep my ice water cold... I filled it with ice and then water and put the lid on. After about an hour and a half, the ice was completely melted. Fail.3. The cup performs better with hot drinks, but still not as good as the manufacturer claims. My coffee stays hot enough for about an hour and a half, but after that it's luke warm and not good.Overall, I am disappointed in this cup, and I wish that I hadn't spent as much as I did on it... It's better than a Tervis for hot drinks, but my Tervis will keep ice much longer than this one will. Frustrating.

Holy cow, the best one that I ever got. I have two now and have one for cold - 7 hours was the longest I needed it so far but usually it only lasts about 2 hours before I refill it, and hot - It has lasted over 5 hours on a long distance trip, when it was still piping hot. I have bought two more for presents and will get more for people I know that will use them

This tumbler is everything! Perfect for cold or hot beverages. The deep green color I chose is matte and beautiful. Beverages will stay ice cold for an entire day! I can go to bed with ice water and wake up to, you guessed it, actual ice in my water! The hole in the lid is ideal for a reusable straw, yet securely closes for a leakproof lid. Best purchase ever!!!

Ordered blue for my dad and received pink... lid also leaks
