    • Keeps water cold for a very long time, lid seal is tight, versatile (swig or straw), easy to clean
Color: Purple Size: 40 oz
I am typical: I have to have my large tumbler with me at all times. I had purchased this same model a few years ago, but I dropped it on the driveway last week, and the plastic flip closure on the lid broke. I did find a replacement lid, but then I thought it would be a good time to get a second tumbler for my car, so I don't have to carry it to and from the house every single time I drive somewhere. This is by far the best 40oz tumbler I've ever tried. First, it fits in my car cupholder without any inserts or converters (not true of some other brands). Second, it is lighter weight than some of the competitors. Third, and most importantly, my water stays cold for a VERY long time in this tumbler; water gets warm much more quickly in the 40oz "Y" brand version I tried. I think the flip closure on this brand's lid is what does the trick so well: it snaps very snugly over the mouth hole, and in the process, it inserts a pin in the airhole, sealing the cup very well. That closure also makes it nearly leak proof, at least for casual use. This is also a much more versatile tumbler. The mouth hole is large enough to give me a good swig every time, or I use one of its metal straws in the car to make it safer for drinking and driving. The 40oz version of that other brand only offers a straw opening, which is very limiting to me. I tried their 30oz version, which has their standard lid, but that doesn't keep the water cold for very long, and it's much heavier. The lid for this tumbler fits snugly in place via a rubber seal ring. There's a lip on the lid to help you remove it (it does take a strong hand, since it fits so well). I used my first lid for at about 2 years, opening/closing it at least 2-3 times a day, and it had only just begun to get a bit looser. The finish on this tumbler is of very nice - very hard to scratch the surface, and it holds its color very well over time. It does not sweat even in our warm summers (high 90's). The metal ring at the top is well-attached and will not come off. The inside of the tumbler is easy to clean with warm water and soap. I use a separate handle, to make it easier to grab and hold, but it's certainly not difficult to pick up as is, if you hold it at the point where the cup starts to get wider. The tumbler comes with 2 metal straws and a straw cleaner - a really nice touch, so you are environmentally conscious (metal straw) with an easy way to keep it clean. We keep several of these brushes handy, so I'm not sure how well this particular one holds up (it got mixed in with the others, we can't distinguish it). But we know at least that it holds up, since the original one is still in rotation from 2 years ago. Finally, quality does NOT have to equate to high price. This tumbler is regularly about 2/3 the cost of the competition I've mentioned, with higher functionality and versatility. ... show more

    • Better than Stanley
Color: Arctic White Size: 30 oz
Review Image by The Nerd Nuggets The Nerd Nuggets
After hearing what's been going on with the Stanley cups, I'm even more glad I went with Beast brand. I have purchased 4 (so far) for these reasons in no particular order: 1. I dropped it and it didn't even dent! 2. When I dropped it, the lid stayed on and my coffee didn't spill a drop. 3. It's beefy AND it looks good. 4. I can customize it with decals 5. Keeps things hot/cold pretty well 6. The lid is super secure 7. Different colors to match with what I wear :) 8. Fits in my backpack's side pockets. 9. No chipping (I've had my first cup for months now; still looks just as the day I got it. I leave it sitting in the sink sometimes and nothing happens. Car cup holder, desks at work, etc.) 10. No metal taste. Idk about you, but I dislike metal tumblers because I swear I can taste the metal. Beast brand tumbler doesn't have that taste. To aid in that non-metal taste aspect, I don't use their metal straws. I instead bought reusable plastic straws on Amazon for about 5 bucks for a 12pack. Still 5 stars because the metal straws are a courtesy not a necessity or deal maker/breaker. I'm not buying this cup for the metal straw, ya know? I do love that you get a straw cleaner, though, those I do need :) Not all cups have the same texture. The black has a smooth matte finish and the white has a glossy smooth texture. The maroon cup is matte but not smooth. The beige is matte and the texture is smoother than the maroon but not as smooth as the black. It don't mind the different textures at all. Makes them pretty unique. The white, being glossy-smooth, is great if you want to add a decal or stickers. I add a Dethklok decal to all my Beast cups and they stick very well. The white cup, however, is definitely my favorite. Eventually, I will buy the light blue one and another color... I'm obsessed with these cups. ... show more

    • Works Beautifully
Color: Rainbow Size: 30 oz
Review Image by Kristina Lundele Kristina Lundele
It keeps hot and also cool liquids cold for long long periods of time. Just don’t top it upside down on purpose because it will leak. Otherwise it’s very water tight. The straws are good quality and it is beautiful. I love the handle that I got extra with it. It’s a must have for sure.

    • Gonna buy more.
Color: Aquamarine Blue Size: 40 oz
Great cup. Cheaper than a stan lee, holds ice longer than a yeet ee. Worth the $. Don't waste your money on the Y brand or the Stan.

    • Great mug for general purpose, not great for travel. Hot liquid shoots the lid off.
Color: Army Green Size: 40 oz
Review Image by M. Bourgeois M. Bourgeois
I had a 30oz from a long time ago but the lid was broken due to poor design (red arrow). So, I saw they fixed that issue and bought a new 40oz. I love these mugs. They keep beverages the temperature you want them at for a VERY long time, they're durable, fit into all cup holders, and are just all around fantastic. Now, while they did fix how easily broken and/or how leaky the old lid was... they created a new problem. The pressure buildup from hot beverages pops this new lid off in about 2 minutes of just sitting on a counter so moving around say in a car or being carried whilst walking would pop it off explosively in a few seconds! Great mug sitting at home or at a desk where you don't need the lid or need to close the lid, if you plan to take your drink with you, stick to cold beverages to avoid laundry or car detailing services. The handle (purchased separately) is a MUST HAVE and I highly recommend if you buy the 40oz that you get the handle with it! I added, since there was a hole there, and it's great for sticking the tea bag string through to keep it from falling into the cup (and completes the grenade look). Although I'm not happy about the lids, I will still buy more in the future and recommend these mugs to my friends. ... show more
