Let me start off by saying that I'm not an influencer, nor have I received anything in return for this honest review. I also gave this tumbler a solid month of daily use before I put in my 2 cents. Also, the pictures were taken in broad daylight. The picture of me holding it upside down is the only time it leaked, but, ya know, I'm holding it full of water, upside down, and even then, only a tiny bit escaped. Through the straw, not the lid, mind you. When the straw was removed and I held it upside down, droplets escaped, one by one. I didn't purchase this for any other reason than to reduce my beverage goblin tendencies, and to support my laziness in regards to washing excess dishes. I bought this because I was tired of having a car cup and a house cup. My house cup is my favorite, it also holds 40 oz, but doesn't fit any cup holder because it's essentially a tank (I copped it on clearance at Walmart 2 years ago for like, $6, and it's the tits). HOWEVER, it really sucks to not be able to take it everywhere, and it's definitely not spill proof. So I had that tank for the house, and my 8 year old 30 oz Yeti for the vehicle, since it fits. I've never used a Stanley so I cannot compare, though I do own the Simple Modern 64oz summit, had it for years, and it's stood the test of time and regular use, both outdoor and indoor. But it's not practical because, although it's very well made, it's massive, heavy, handle-less, and rolls out of the passenger seat onto the floor and out of reach, leaving me parched and annoyed. This tumbler is well-made, from the unit itself to the lid and straw, and the price point is beyond reasonable. I'd have paid $40 for it because of how well it's preformed. The handle is sturdy and comfortable, and it supports the full weight of 40 oz of ice water easily. I've dropped it several times and the powder coating hasn't chipped, nor has the metal dinged. Although most wouldn't think if it, it is SO nice to decide where I want the straw to be in regards to where and how I'm sitting and what hand I'm reaching for it with. It washes up easily. It's not obnoxiously large and it's overall appearance is low-key. It keeps my tea cold and fresh for 2 days indoors. I've left it filled with ice water in my vehicle for 2 days (in early June in the south, mind you). I got super thirsty after a grocery run and took a sip. It was room temperature, if not a skosh cool, but in no way was it warm, even though the cup itself was. It's fallen out of a backseat cup holder and laid on the floor for well over an hour without my knowledge, and although a few drops escaped from the straw, the carpet of my vehicle was dry, and the tumbler was still full of ice water. And, ya know, it keeps you hydrated because you can always keep that thang on you. I ordered the almond color. It's really more of a very light beige. Or coffee that's mostly creamer. A lot lighter than you'd think. It's definitely that boring popular aesthetic hue that everyone's so into, so if that's what you're going for, it's spot on. All in all, I really really REALLY like this tumbler and I'd definitely recommend it. Then again, Simple Modern products haven't ever really let me down, so it's not a huge shocker.
