I'm loving it!!!

So I didn't understand all the hype around the Stanley cup and had honestly never heard of them before, but totally decided I wanted one once I saw them haha. But I didn't care about name brands or whatever, so have no problem with getting an off brand, I just wanted a gigantic cup to keep my Mountain Dew cold during the day, and that's what this does. I was using an off brand Yeti style one, so only about 22 Oz or so? Which was totally fine, but I was ready to move up to something bigger so I wasn't having to get refills as often lol. Plus I'm using that old cup for water now.Anyway, it comes with a metal straw, it's really thick and sturdy, probably be pretty dang hard to break lol, then it has a rubber cover for the straw, which idk why, but I've been using it since I got it. The straw is straight, and the rubber piece has a small bend in it to so the straw isn't just completely stick straight, which I like. The lid screws on, which is nice and makes it a lot harder for it to bust open or something. The opening in the lid seems nice and big, but I've only ever used the straw so no idea what it's like to drink from. It's got a rubber piece you can use to close it, and then it pops off and you turn it so it's not in the way when you want to drink from it. I personally keep mine open at all times, especially since I have the straw on, but it seems like it's a nice seal and not too easy to break or have pop off, so again seems like it'd be hard to spill your drink.It's TALL, obviously, but not very wide and will fit in your cup holders in your car, but it honestly doesn't seem THAT big once you actually have it and then you get used to it quickly. Like I said, I was using just a 22 Oz Yeti cup for a while, so I thought it'd take some getting used to literally doubling that, but honestly it wasn't. Lol I will say that I keep thinking my water cup is empty or close to it because I've gotten used to the weight of this one, so anything else feels super light and I'll think it's empty lol.Anyway, I haven't had any complaints about it keeping my drink cold. I tend to fill it up with Mountain Dew, yes I'm aware you're not supposed to have soft drinks in it but as long as you don't seal it up and it's able to breath it's fine, like I said I use the straw at all times so I always have to opening on the lid open. Yes, the soda does get flay eventually but imma be honest I don't really mind. It's all just up to personal taste and I'm fine with it, and honestly usually finish it before it gets flat anyway. But it does keep it cold. I don't like using much ice anyway, so I usually just pour it directly from the bottle that's been in the fridge, and it'll stay pretty cold for a really long time. Since it's soda and I do tend to drink it before it gets flat, I'm not really pushing it to its limits and having it keep it cold for like 24-48 hours lol but I have had it before still be cold after being left out overnight. And when I do put ice in it, it will take a LONG time for it to finally disappear lol.So is it on par with the Stanley ones that are wayyy more expensive? No idea, I've never used a Stanley. Will it keep your drink cold for a while and stand up to some abuse and keep your drink from spilling everywhere if knocked over?yeah. Sure. If you're just like me and using it for hanging around your house and you're just wanting to cut down on getting refills lol then yeah go for it. It'll get the job done just fine. I like the handle, too. It's sturdy AF and makes it way easier to carry it when it's full. I've never come close to dropping it, and I am definitely clumsy lol.Anyway it's a nice cup, the end. Is it as good as the Stanley? Eh probably not, but it's fine for what it is and it's really cute, too!! I love the color, it's super vibrant too. So it's certainly on par with the Stanley in that regard!!!

Buy it it’s so worth it

This water bottle is amazing at keeping drinks cold and hot for long periods of time. It’s perfect for work and makes a great grab-and-go option when I’m in a rush. The design is convenient and easy to carry, and it fits perfectly into my daily routine. I love how reliable it is throughout the day, whether I’m keeping water ice cold or my coffee warm. Definitely one of the best water bottles I’ve used and a must-have for anyone who’s always on the move.

Durability and without the Wallet Sting!

Ordered three Gpeng ©️ Stainless Steel Insulated 40 oz Tumblers (Water Bottles) with Handlewith Straws and Lids on May 7th and received on May 9th, 2025 in the colors Black, White and Pink; sold by G&F International. Gifted as presents to my sister who lives in Florida.I thought I would jump on Amazon's $10.49 "lightening" sale, as a "Just Because I Love You" expression. They were surprisingly well received, which my niece claimed the Pink tumbler and my nephew immediately claimed the Black tumbler as his own. The trio enjoyed the convenience, ease and transportability of their Gpeng ©️ Stainless Steel Insulated 40 oz Tumblers. As other reviewers have reported, maintaining ice cold drinks in sweltering heat wave was a welcome treat during family gatherings, while driving, running errands, or bed side convenience. Fortunately, it's soon to observe outcomes of potential wear and tare, such as rust, dents, or stability issues. However, my sister reported the straw began chipping at the mouth piece. This must be a common flaw in straw designs, I had similar experience with the Stanley brand. Therefore, precautions were taken in advance and replacement straws (metal with silicon tips and extended silicon straws with brushes) ordered to avoid future frustrations and inconveniences.Although described as "dishwasher safe," my sister opted to hand wash for ease and to prolong product integrity. Furthermore, two 16 oz. water water bottles filled the tumblers to capacity, or one 16 oz. water with appx. 16 oz. ice; and fit well into vehicle cup holders without slippage. Without offense, common sense and care was used not to over-fill and avoid tumber spillage for water retention. Thus far, the Gpeng ©️ Stainless Steel Insulated 40 oz Tumblers quality met my sister's daily demands. For those looking for a budget friendly option to escape capitalist greed, take a leap of faith and enjoy the affordability, durability, comfortability, and convenience of Gpeng ©️ Stainless Steel Insulated Tumblers. Happy Shopping Fellow Amazonians.🌴 ❤️

Great hydration vessel

I got the 40oz for work. The green is beautiful and exactly what I was expecting. I mix drink powders in the cup and I’ve never experienced it leaking. I like that the straw can be put down for traveling /preventing spills it is a unique feature.
