Simple Modern 40oz Tumbler: Is It Better Than The Stanley?

I am nothing if not someone who loves to be influenced. After I shared my Stanley tumbler review, I started getting messages asking me to review the Simple Modern 40oz Tumbler (linked HERE). I decided against it, because I really don’t need another cup. And yet…here we are! I’m so glad I succumbed to peer pressure, because this is my favorite water tumbler yet. I’m going to share all of the things I love, along with a slightly annoying snafu with my order. I also recently ordered a BruMate Era tumbler that arrives next month. When I get that one, I plan to do a master post comparing all of my cups — including a test of which keeps water coldest the longest. Let’s get into it.

Before I bought my first large water tumbler, I didn’t get the hype. But having a huge cup really does help me drink more water. When I go out of town and forget to bring a tumbler, I notice how much less hydrated I feel. Now that we’ve established that a giant reusable cup can be good for your health, it’s time to determine which you should get. The first difference is the price. The Stanley 40 oz. Quencher H2.0 FlowState Tumbler cost me nearly $61 after taxes; in comparison, the Simple Modern 40 oz Tumbler was only $32.09. This is the most significant consideration, in my opinion — it’s nearly half the price and serves the same function. If anything, I’d pay more for the Simple Modern cup.I’m going to address other factors.

The Stanley cup weighs more than the Simple Modern, and it’s also taller. I personally find it easier to lug the Simple Modern around, but the contrast isn’t significant enough to make much of a difference. The biggest advantage is fitting two Simple Modern tumblers in car cupholders, which I couldn’t do with the Stanley.

The Stanley and Simple Modern are similar enough in design that I don’t feel as if I’m missing out carrying the cheaper Tumbler. If anything, I prefer some of the colors that Simple Modern sells. I liked my Reduce tumbler, but felt that it lacked the same sleek design as Stanley. This is a great alternative.


This is where the Simple Modern really shines. If you turn the cup upside down, it’ll leak, but I haven’t noticed any problems when it’s rolled on the side. This simply isn’t the case for Stanley. One of my biggest gripes with the cup is how quickly it leaks water, which is an issue Simple Modern doesn’t seem to have.

I’ve only had the Simple Modern cup for a few weeks so I can’t speak to longevity, but I will update this post once I’ve owned it for longer. My Stanley has its fair amount of chipping, although I wonder if that’s because I bought it in such a light color. When I spent $60 on a water tumbler, I assumed that it’d be more durable.

This is anecdotal because I haven’t officially tested either cup, but the Simple Modern seems to keep water just as cold — if not moreso — than the Stanley.

Final Thoughts

I know this reads as a glowing review of the Simple Modern tumbler, so let me share the one thing that was a bummer. When my cup arrived, there weren’t any straws even though the product listing advertised two. (A quick glance at the reviews revealed that I wasn’t the only one.) Amazon generously refunded me, but I was left without a straw and am now using one that doesn’t quite fit the cup. This doesn’t have anything to do with the actual product, but it was a tiny frustration. I used my husband’s tumbler for all of the photos in this post.

    If you have the actual straws that go in it then it doesn’t leak at all upside down! I purchased my first SM 40oz at target and it only came with one straw in the cup. I bought my second on Amazon and it came with 2 straws. I don’t have a Stanley but I really love my simple modern. Even my 3 year old loves it so I bought him one in his own size.

    Order direct from Simple Modern. The best customer service I have ever experienced. Sent them a question on a cup I was considering for a relative and their answer went above what I expected. Even included photos. Just ordered and can’t wait to see how they like it.

    Definitely, don’t give it a final thought until you purchase from the actual Simple Modern website! I have no less than 20 of the Simple Modern cups tumblers and more and I absolutely love them and they have the best customer service. If you would have bought the cup off of the actual Simple Modern site. They would have sent you a free cup to replace it and had you keep the one you had. customer service is unmatched. But 100% agree Simple Modern is definitely better than Stanley

    I have had my SM cup for about 6 months or more and it is the best cup I have ever purchased. It’s not too heavy, the design is sleek and my water stays cold ALL DAY LONG. I have even dropped it on the concrete and while it’s got a scuff, that’s the only thing that happened to it. It’s still in tact and works perfect!

    Simple Modern has one of the best customer service departments I have ever done business with. I ordered my 40oz. Trek Tumbler. I ordered mine through Amazon and I reached out to them, through there. They were very accommodating and I’m sure if you reached out, they would send you some straws. I have been buying this brand since before the 40oz. cups were even a thing. I LOVE my Simple Modern cups!!

    I agree that SM is supreme! Use the straw that should come with cup and you won’t have any leaks.
