Well made, easy to clean, and no leaks.

It’s very good. Keeps ice for at least 18 hours. Stays super cold, doesn’t leak, easy to clean. Works great for hot liquids too but I would be worried about the straw as I become more aware of microplastics and begin to eliminate them from my life they are literally everywhere if you actually analyze what they are in and how the break down over time we have a really tough uphill climb. I would like to see this straw replaced with something that will never break down and get into our system period. We would ideally have to use only a product with steel insulated walls and no plastic contact, not even the o-ring. Even those break down and get into our liquids over time and that amount of time is very short. It doesn’t fit in all cup holders because of the cup holder depth, if it’s a deep cup holder then the handle gets in the way. Its versatile to an extent I guess, but it becomes cumbersome quickly depending on the application. I think it’s good for hangout at the pool or beach but beyond that its size and shape start to annoy pretty quickly. It’s also heavy if you’re loading with ice and liquid and if you add chopped fruit or veggies then you’ve got yourself a pretty weighty jug rapidly. Its also very tall because they try and accommodate standard cup holders so keep that in mind, it’s easy to knock over and if it’s full of ice, liquid and chopped fruit and veggies for flavor enhancing it’s quickly like carrying a small carryon or cinder block with a handle. Overall though it’s a tank, keeps liquids cold as heck, doesn’t leak, sturdy, and easy to clean but quickly can feel like you’re carrying a 5lb infant around, that’s top heavy, not stable in many standard cupholders becoming a cumbersome dumbbell quickly. Speaking of dumbbells it can be used as one in a pinch

Excellent tumbler – vibrant, practical, and leakproof

This is my first Stanley cup and I am loving it and haven’t stopped using it since it arrived! The colour - Vivid Violet - is so vibrant and eye catching and looks even better than I could have imagined. The quality of the cup and the design features are outstanding and well worth the premium price. I do believe that you generally do get what you pay for, and in this case you are getting a premium product made of high quality materials and that is built to last. The stainless steel insulation does exactly what it is supposed to and effortlessly keeps your drinks chilled for hours. The fact that this cup has a flip straw lid which is leak proof really is the stand out feature and I have had no leaks from it whilst carrying it in my bag or when I knocked it over. You do have to make sure you line up the lid when putting it on to ensure that you have the flip straw opening at the side you want to and at first this took me a couple of tries to get right. The handle is well shaped and makes carrying a full cup easy. This is a large cup - 1.18L - but it’s a great size to help you stay hydrated. Highly recommend.

High quality product from a Legend company in thermal drink containers

Stanley is the gold standard of thermal drink and food storage, This cup fits well within their tradition of excellence. It checked all my boxes. Leakproof when closed flip up, removable spout All day temperature control Durable Easy to clean Side handle Available Colors Large capacity Fits in smaller car cup holders (my 300C cup holders are rather small, under 3") One key feature for me was a comfortable side handle, I get tired of holding large insulated cups around the body. I'm not a fan of the other current Stanley insulated cup so prevalent, with the drink straw, because even closed, it leaks a lot upside down on sideways. This is the one! My only complaint, restating what others have said, is that you exchange the secure seal of a threaded cover, for the ability to adjust where the spout aligns with the handle, that a press fit cover affords. On this cup the spout aligns about 45 degrees away from the handle (or 180 deg from that), due to where the threads stop. I don't find it terribly annoying, but I would like it close to 90 degrees from the handle on either side.

Pros: • Keeps drinks cold for a long time • Stylish and trendy design • Comfortable handle for easy carrying • Large capacity, great for all-day hydration • Durable and well-made Cons: • Can feel heavy when full • Lid may not be completely leakproof if tipped Overall: A must-have if you want a reliable and stylish tumbler.
