COKTIK 40 oz Insulated Tumbler with Straw, 3 Lids (Straw/Flip), Vacuum Insulated Travel Mug Stainless Steel Tumbler(1Pack,Black)

Bought one for my husband and another kind for myself but Loved his so much that I ordered myself one right away. I love the fact that it's slim but tall so fits in my cup holder at home as well as in the car. Ice stays in it over night without melting away and leaving the drink watered down. Would definitely recommend. It came with 3 different tips so i can switch then out when I'm drinking coffee or when I want to drink cold beverages with the straw. Also came with cup cleaning brush and straw cleaner.

I’m totally not onboard with the outrageous prices of name brand water bottles - I got this for my son so he can slide into the spot for water in his backpack- this thing is a beast but still fits in the slot! Keeps water very cold! Definitely recommend esp for the price!!!

I am a tumbler girl. I have a minimum of 30 tumblers from a bunch of different companies. I ordered this one because of the look of it, and b/c it's 40 ounces. I was extremely surprised by the quality of it. It is sleek, smooth, and does NOT leak when the straw is not in it. It comes with three lids and an awesome steel straw! It doesn't hold ice as long as some others, but it holds it long enough that the difference is minimal. I have paid twice as much for far less quality and certainly not 3 lids! Plus, the straw is thick and sturdy. I wish I could buy more of the straws too. Do yourself a favor and buy one of these! You'll love it and will not regret it. ❤️

The media could not be loaded.  However this only holds 2 , 16.9 oz bottles of water which is 33.8 if I did my math correctly.No way it’s a 40 oz. Other than that it’s wonderful. Fits in my backpack side pocket and stays cold and the built in straw lid is def leak proof.

Have owned many insulated cups, including the pricey Yeti. Put a couple cups of ice into cup and added cold juice and soda water from fridge and finished drink. Left it on the counter overnight until the next day in the afternoon and was gonna wash it out and make another drink. The residual ice was still on the bottom, so I made another drink just like it and repeated the process. Woke up this morning to wash the cup again and SAME ice is still in the cup! I’m gonna wait until this afternoon and see out if curiosity how long it will take for it to melt!

Very nice! It's big and still fits into cup holders! Keeps drinks cold! I love it! Definitely recommend!

This tumbler comes with everything! Several different lids (with straw, without etc) even a cleaning brush! These guys have thought of everything and so far no leaks!!

Okay cup, fits in cup holders. The lid with the separate straw leaks really bad (as expected) and it's surprisingly HARD to screw off. The lid with the built in straw is hard to drink from. It's OKAY.

I love this so much!It's almost too good! I went to work at 8am with tea that was too hot. By 4pm it was still too hot! Keeps the heat amazingly wellBoth the leak proof lids are leak proof as advertised. The non leak proof one is still good just have to be more careful.Love the lil cleaning kit that comes with it. Makes it really easy to clean the straws.It's massive! Which is exactly what I wanted.Instead of bringing to flasks to work now I only have to bring one.Couldn't be happier with it
