COKTIK 40 oz Tumbler With Handle and Straw Lid, Vacuum Insulated Travel Coffee Mug Stainless Steel Insulated Cup for Beverages, Leak-proof, Cupholder Friendly(Dark Night)

I initially just needed a water bottle with a straw. Also wanted it to be insulated to keep hot and cold temperatures for a while. I really didn’t want to spend the $45 for a Stanley cup 40oz so I looked up other options on Amazon. This cup has everything I was looking for and it’s half the price. It’s completely sealed and insulated so it doesn’t leak and I don’t feel the heat of the contents. I am pleased that it also fits in a cup holder. Also, it comes with a sponge bottle cleaner, straw cleaner and an extra silicone seal. My new favorite water bottle.

I love this cup. The color is so beautiful and the quality of the cup is great as well. It does not leak at all and keeps the drink cold and hot for hours. Very good quality for the price. Just like the Stanley cup.

As for the color, I got pink. It is a very soft pink that almost looks cream in certain lights; so beautiful! The cup itself does not come with a protective sleeve for the bottom, so that will need to be purchased separately. The cup holds ice wonderfully, and thus, I didn't have to add any ice in my cup for over two days. The cup itself is very durable, resistant to scratches, and must be hand-washed. If you're looking for a 40 oz. cup that's of Stanley quality for only a mere fraction of the price, this is the perfect fit for you.

This tumbler is well built and I like it a lot. My only issue is that I bought a 40 ounce and it’s kinda heavy when full. I should have ordered a 30 ounce and probably will. This tumbler keeps ice frozen in my drink for at least 24 hours. It’s very pretty and I like it, just a tad heavy for me when full of ice and drink.

Very sturdy and ice will last 2 days in it! Kinda heavy tho! But super cute and a great cup overall!

I've been using this water bottle everyday for the past 6 months. The straw cracked at one point when I dropped it, but it's still usable until I get a replacement straw. It came with its own cleaning brushes which has been nice. I got the white one. It has some marks from when I droppped it many times, but to be loved is to be changed. It was spill proof at first, but after awhile I think it leaks when it gets knocked over. Only when the straw is in. But I think this is a really great tumbler for the price. Great quality. I'll probably buy it again when I need a new one.

Ordered a couple of these to give them a try and am already putting the other colors in my cart for later!It’s a fair price given the size, lovely colors (I do hope for more variety in the future), spill proof, sip or straw, and seems to hold temperature fairly well. I also loved the fact they came with lil extras including a silicone boot, straw, cleaning brush for the straw and a sponge to clean the cups themselves!

Love the cup! The lid was a little hard to twist off at first. I opened the drink hole and that actually helped. The cup gets heavy when filled. Keeps my drink cold!!! The cap that the cup fits into was a little misshapen when I took it out of the box which made the cup a little off balance, but after it being on for a few days, it fit well and the cup now sits flat. The handle really helps in lifting and holding the cup considering how heavy it gets when filled.
