Exactly what I was looking for
I was originally looking for an insulated tumbler to drink water out of as I find that having a cup with a straw helps me meet my water goals more easily. When I saw this, it was the perfect match! Large size, sleek design, AND can be used as my go-to boba cup (other travel boba cups are either plastic, ugly, small, etc.). I’ve had it for a little over a week now with daily use, and it’s held up well. I don’t find that it’s prone to scratching or anything like that.Pros:- 24oz size is perfect for me- sleek, matte black design- similar construction to a single-use iced coffee cup (am I the only one who feels things taste better depending on the cup shape?)- no plastic components (though it came in a protective plastic sleeve)- keeps drinks cold for a few hours (there are openings, so it won’t be as effective as an air-right container)- rubber sleeve at the top of the straw prevents me from damaging my teeth, and it’s removable so it’s easy to clean- straw reaches all the way to the bottom to get every last drop- rubber seal in the cap helps prevent spills; only real spillage comes from the hole at the top/liquid stuck in the straw- bonus matching straw brush is a nice treat, especially if you don’t already have one from other reusable strawsCons:- 24oz is good for my daily water intake, but if you’re buying it solely for boba, it is quite large and bulky- solid black design is super cute, but the matte finish means it’s finger print galore- the rim of my tumbler came a little scratched up, but you can’t see it when the cap is on so I don’t mind- faint metallic taste when drinking water, but I haven’t noticed it altering the taste of my milk teas/fruit teas- as it’s made of metal, it is a little loud if you set it down haphazardly, as you would experience with any insulated water bottle

Scratched Right Out of Box
While the overall aesthetic is nice, the tumbler came with multiple scratches on it right out of the box. Very disappointing for a $20 tumbler to come damaged, but doesn't seem that uncommon based on other reviews.

Buy this ASAP
I am in love with this bumbler! I would recommend it to anyone who loves boba and is conscious of their environmental footprint.The only thing is that on the seller’s website I asked them if they had a closing lid because I was worried abt spillage so that’s why I would say this isn’t entirely leakproof. If you’re really worried about that, on the seller’s website they have a holder for the cup and that would probably reduce the risk of spillage. But the actual lid is very tight.Many people complained that the seller sent them the wrong color, that wasn’t the case for me, but if you really are concerned about that, go to the seller’s website bumblercup.com and you’ll be guaranteed the right color.All in all, I know this might be a bit obnoxious of me, but I wouldn’t care about the negative reviews they’re more about personal problems than the actual product itself.So if you have no doubts, and are really passionate about boba and the environment go ahead and purchase the Bumbler Cup!

Would not buy again
I do like the tumbler for the most part. I wish I would have paid more attention to the description. It is a little large for me. The big think that bothers me is the straw is painted. The picture does show it the same color as the cup. Personally I will not use the straw as I am concerned about the paint coming off or the potential for chemicals in the paint contaminating my drink. Having a stainless steel straw and painting it seems kind of silly and it cost me more to purchase a straw that was not painted. Would not recommend.

Works great, scratches easily
Whatever they have this coated with scratches VERY easily. There is nothing wrong with functionality. I will say, I did pop the silicone part of the straw off and attach it to the bottom of the straw to prevent it from coming out of the lid. Just disappointing that the cup is covered in scuff marks due to poor quality coating.

Color scratches off easily
Love the tumblers so much, I bought one for everyone special to me, baby sis, mom, aunts, friends.. However, my only complaint is that they scratch easily. So you have to be really careful with it, or the color scratches off, and all you see are metal markings. I tried to find a "sleeve" or a "bottom" protective cover for it, but such things don't exist yet, or if they do, I haven't found it yet. Overall, the cup is super cute and functional. Just don't like how easily the color scratches off.

So cute and high quality!
I’m IN LOVE with this tumbler. It’s leakproof and even comes with a cap to go over the straw when your not using it. It stays cold even longer than my Yeti glass and I love that the straw is wide enough to drink thick liquids like smoothies and frozen coffee drinks. Highly recommend
