30 oz. Tumbler-Stainless Steel Tumbler - Travel Coffee Mug-Double Wall Vacuum-2 Bonus Lids - Splash Proof - Keep Beverage Of Your Choice, Cold or Hot.

I really am enjoying this tumbler. I utilize it for the main thing that I drink, which is water. I don't like my drinks really cold, so I don't put ice in my tumbler but I have utilized I for coffee and the tumbler kept my coffee hot for the 6 hours that I allowed myself to sip on it. The quality of the tumbler is nice, although I found it to be a bit slippery when holding. I found a handle on Amazon and purchased it to use with my tumbler so that I don't drop the tumbler and spill my beverage all over myself. I think providing something that allows you to grip that tumbler would be a nice addition. I use this with a stainless steel straw (purchased on Amazon) and it works well. the tumbler does come with two tops but I only use the one that allows you to use a straw and when the straw is not in it, it can close. I don't feel as if the open top promotes you trying to keep your beverage hot or cold.

I was looking for a large cup that would keep my ice throughout my work day. I was stopping at a gas station almost every morning for a .50 cent big gulp of ice before this cup. It keeps my water cold all day and is a good reminder to keep drinking water throughout the day.

A bit top heave for transport in the car-hard to pick up with one hand. The opening to drink out of is too big-tends to cause dribbling

Loved the cup but expected the lid to not leak. If tipped over the lid only slows down the leaking. Overall it is a great cup but really should have better seal.

I've been using the cup for my coffee since we all know how quickly coffee typically losses its heat in a regular mug. My coffee was hot for hours! I like the two lid option for traveling and the slider lid is large enough for a straw! The lids have a tight fit but the slider lid seems to be more snug. The cup itself (when full) is fairly light compared to other stainless cups. I am very pleased with this product and it's price.

The cup is fantastic. I bought one as a present and when my granddaughter told me how great it keeps cold drinks cold, I purchased a second one for myself. I fill my cup with ice and water and there is still some enough ice more than 24 hours later, even though I have opened it and added water a couple times during the day. I like my water very cold through the day and overnight.

Keeps coffee hot all morning, although when full, it is heavy.f

The Tumbler was a hit with the person I gave it to. Infact they were estatic over the mug. I ordered 2 more of them for friends who will use them everyday at work.The fact that they come with 2 lids was great.Yes I would buy again from the seller. Very nice people and very interested in how you like their product. Well worth buying
