A Must-Have for Fall!
I absolutely love this tumbler for Fall time!! It’s so cute with the black-on-black bat design — total chef’s kiss! What I love most is that if it tips over, it doesn’t really spill (just a tiny bit out of the straw), so minimal leakage. Perfect for cozy autumn days and keeps my drinks just right. Highly recommend for anyone who loves festive and functional drinkware!

Favorite Cold Drink Tumbler!
This Tumblr is amazing, easy to clean keeps all my drinks cold for hours, no leaking has happens so far I love the Halloween ghosties, on the white color. It has a slip resistant silicone at the bottom. It is dishwasher safe but not for microwave. Super cute.

Great Cup
Love the color and functionality. Holds water well and stays cool. Decently easy to clean. The straw area gets a bit annoying. Sometimes the lid leaks.

Cute and user-friendly!
I love this Tumbler! I’ve had several of the other big brands and feel like this one ticks all the boxes for me. I love that it has silicone on the bottom so it’s not clunky when you set it down, I love that you can stopper the straw so you can shake in electrolyte packets to your water, the color is super cute! Unlike other major brands, the lid does not get stuck on! Not a hassle to clean. I love that I can just throw in my bag and go!

After a year of use, I wouldn’t buy again, but I don’t regret it either.
Pros:Fits every cup holderStylishHas rubber feet so it’s not loud when you set it downHigh quality finishDoesn’t leakHandle is greatLove the straw material so you don’t hurt your teeth when you accidentally hit them with the strawGreat temp controlEasy to cleanCons:Way too top heavyBecause it’s top heavy and has rubber feet, it falls over a lot and is VERY loud when it falls. Like I cannot understate how loud it is ALL. THE. TIME.Sometimes it makes a loud gurgling noise when you drink from it.

love all cups by simple modern! got this one for my friend and she loves it. fits in a car cup holder, easy to clean, has a good locking mechanism, straw can be a little difficult to drink out of, ice retention is as explained.

Stylish and leak proof
Love the size and it's super cute, but took some time to get used to. This is my adult bev cup and it's great as it holds a ton and when the plunger thing is down it's definitely spill proof. Pretty easy to clean, has more parts to disassemble before cleaning but, all good!
