Zukro40 oz Tumbler with Handle and Wide Straw, Double Wall Stainless Steel Insulated Cup with Screw on 2-in-1 Lid, 100% Leak Proof, Keeps Drinks Cold 24 Hours, Dishwasher Safe - Bluewave

I am a cup/tumbler addict however I have a price limit. I can’t not find myself to spend what these brand name tumblers/cups are going for. I purchased this tumbler April 2023. I do use it almost everyday, it is one of my favs but what bumped it up to possibly #1 and encouraged me to write this review, just like most I am on the water kick. I use crushed ice and water from our fridge. I always make sure I have something to drink on my nightstand because I wake up thirsty. Last night I made my water like normal in this tumbler. For some reason I did not put a lid on the tumbler, I just placed the straw and went to bed. That was around 1230am-100am. I drank my water finished it off this morning around 830am to take my meds. I had an appt today and like usual I was running late instead of grabbing my usual go to tumbler I went with another and left the pink one that I used last night on the kitchen bar. We left our house around 12pm, the tumbler was left on the bar with no top, I even removed the straw. I meant to pour the ice (that is what was left) out before we left but forgot. When we got home around 730pm, the picture is the ice still left in my tumbler. So this ice has been in this tumbler 19-20hrs with no lid on top (just reference we live in Eastern North Carolina, yes A/C was on today)…… My husband and I were amazed that there was still ice in the cup and very little melted…. I definitely recommend this cup 100% and I am definitely going to purchase another! )For reference where the tumbler goes from round to narrow, that entire narrow part of the tumbler was full of ice…….. Buy this you will not regret it, by chance any family or friends read this, my birthday is next month (Aug) even though I am purchasing another, no one can have enough tumblers especially if I get the hubs on the water kick 😉🧊💧

I ordered this tumbler because it is 50oz and I thought I wouldn't need to refill as often, because it is cup holder friendly, and of course because of the pink cheetah print! But as it turns out, the straw is pretty wide and I actually end up drinking more water out of this and needed to add more water to it a few times over the day. Holding ice: I filled this to the top with ice, then filled it the rest of the way with water. I added cold water to it 4 or 5 more times in an almost 36 hour period, and it still had ice left in it! For that 36 hour period, it was mostly in my air conditioned house (inside temp ranged between 72° and 78°), and outside in about 75° heat (in the shade) for about an hour. I don't mind the bigger straw, it helps me drink more water and it's big enough that it can handle a smoothie, but I wish it was a little bit longer and was curved. And I love the cheetah print! As you can see from my pic, the handle and the straw tip are a soft pink but their pic of the pink cheetah shows the pink as being a darker, more vibrant pink, so I was slightly disappointed that the color wasn't 100% accurate.

I chose this tumbler/mug because at 50 oz it can hold enough water to keep me hydrated and still hold a good amount of ice. I need less refills due to this. I get many compliments on the colors as well.

Kept cold overnight. 4 stars because it's more purple than brown, but still pretty neutral so I'll keep it. Bananas for scale for those of you who have a hard time picturing the size of things like me!

The Tumblr came with two lids. One on it was already cracked seems to be the weak point of this Tumblr other than that it keeps whatever you have in it cold for a very long time. Very happy with that. it really can’t take a tumble so they should call it something other than a Tumblr just saying.

WOW!!! I'm amazed how long my ice water is actually Ice Water in this cup!!! I can fill it with ice and the water, add more water about three more times, and still have ice at the end of the evening in the cup!!!

I live in Florida. It keeps my drinks cold for probably eight hours a day. I do add fresh ice about halfway through the day just cause I like it really cold, but it will stay cold all day and I live in a very humid place.

This is the best tumbler I have ever owned. Keeps my drink cold all day even when I leave it in my vehicle for hours.I loved it so much I purchased 2 more
