So much better than my Stanley! Love the color and size, fits perfectly in the cupholder. Everything comes apart for easy cleaning, the straw part is strong magnetic. It did take some effort to get the top to twist to lock/unlock, but it seems to have gotten better after using it more. Drinks stay cold for so so long and hot drinks stay hot. Definitely worth the money! The locking actually works and not a drop leaks out, but even if it’s unlocked barely any liquid comes out if it is accidentally knocked over

I am absolutely in love with this tumbler! I have not been interested in jumping onto the Stanley bandwagon. I had plenty of cold cups I already wasn't using. I had also recently bought another smaller steel water bottle in another popular brand that I thought I preferred. (and then I only used it once, fearful part will break). So I saw ads for this gorgeous Brümate Era tumbler and I was in love with the design and the fact that it was leak proof! I was sold and have been eagerly waiting for mine to arrive since. Arrived today and wow it's beautiful..The color is even more amazing in person! And it's "soft". Smooth. It feels nice and it very nicely shaped, and comfortable to hold. I am sure it will fit in my car drink holder nicely. Did the "turn upside down" test, and sure enough there is no leaking whatsoever. I admit I haven't tested this much but I have read alot of reviews if people just throwing it in their bag without worrying. That's perfect for someone as clumsy as me. Always a mess no matter what I do. The straw is metal which really is better especially when your bottle is also metal. I love the silicone drinking and, as metal always hurts my teeth.. This is the perfect solution. The lid is easy to remove, take apart, and clean, including removing the straw. Very streamlined, very simple design..Beautifully made. As far as how long the ice stays frozen...what the packaging says is that the more ice you add the longer is stays cold..I don't need it to last multiple days. I simply need it to stay cold all day, and given the double walled insulation I have no doubt my drink will stay cold all day. I was worried about the weight. It's a nice metal cup, there is some expected weight but it seems like it is perfectly balanced weight, it that makes sense. Filled with water/ice it gets heavier. But...what else can you expect with a 40 oz metal cup with ice and liquid? One more feature that sold me on this cup was being able to add carbonated beverages..I drink a lot of sparkling water and am excited this is designed to hold that as well no problem. the included instructions state that pressure will build up with carbonation, and to open slowly to break the seal. I look forward to being able to show this cup to others. It's wonderful and I'm so glad I purchased it!

This is the best tumbler I own, hands down! The look is unique and functional, the build quality is solid. The straw lock system is one of a kind and does not leak at all, plus it's easy to clean as well. It holds both hot and cold temperatures well. The color selection is nice as well, though I would like to see a few more brighter colors. Get yourself one or two!

I have been through them all Stanley, Owala, Yeti, S|M, Walmart Ones, Target ones, No name ones and none of them have made me this happy! Not only the color is perfect, but the way it fits in my hand, and the locking system so the water never spills, makes me want to refill it every time it runs out of water 😍 the one thing I kinda am getting used to is the rubber tip on the straw but I love that the rest of the straw is metal since it is much more hygienic and gives colder sips! DUDE JUST BUY IT. Especially if you’re a parent! PSA: (Just remember to buy a bottom-protecting thingie just so it doesn't scratch up when you put it in your car cup holder.)

Well made, sleek 40oz design which is more modern than other 40oz mugs. The color is a vibrant pink, nice grip handle and very sturdy construction. I bought this one called Era because of the leak proof top which works very well, no worry about spills in the car! I also bought it because I really like that it can be completely disassembled for the dishwasher. A good investment, a good mug and I'll be buying another one - one in the dishwasher, one being used!!

After my expensive water bottle with a straw (we won’t name brands) fell over in my bag and left my laptop in a literal puddle, I had to find a solution. Carrying my drinks is not an option. An online influencer was promoting this product and it did not disappoint. I have been using it for months and I love it more everyday. A couple times I overtightened it and wondered if I would ever get the lid off again. It doesn’t need to be screwed on super tight to be leakproof. The lid had a grippy texture so it *usually* twists off effortlessly unless you hulked it closed. Don’t do that and this will be your favourite cup so you can finally get rid of all those other cups taking up so much valuable kitchen space! I also have the leakproof hot cup and it’s amazing too!

I was skeptical about whether or not the tumbler would actually be leak-proof, but it is! It’s super easy to use and such a beautiful, vibrant colour! It keeps my ice water cold for 12 hours at least. Definitely reccomend!

THE BEST tumbler on the market (in my opinion). I have tried Owala, Stanley, and YETI and I love this one the most! So happy I was able to get my hands on it in Canada

Love this tumbler. The locking straw works perfectly. My daughters and I fight for it. Keeps my water nice and cold.

Hermoso y realmente a prueba de fugas. Ideal para la oficina. Muy elegante.
