I love this cup. The quality is excellent, it's so pretty and it's easy to wash and comes with different straw options and a straw cleaner!!! It's so cute and it's nice and big and holds lots of water. Also fits perfectly in car cup holder. Why spend $65 on a particular brand when you can get literally the same thing maybe even better for less than $20. I actually bought this cup for my daughter for Xmas but ended up keeping It for myself once I opened the package lol! Great product.

I received this mug yesterday (black). I washed and dried it by hand and put cold water from my refrigerator while steeping hot tea to mix with it and some ice. I put the cap on and you can't twist it too tight because you can't get it off. I tried, my 17 yr old son tried. I tried to soak it in warm water, was a nope. Dried it off and put in my freezer overnight then let it thaw out for about 45 minutes. I was able to get the top off. So my suggestions are to not screw the lid on super tight and if you do, empty out the cup, stick it in the freezer, let it thaw out and you should be able to get the lid off. As for the cold/heat time, I haven't tested that yet. I'll try to report that another time.

Edit to add. Added ice almost to the top of the mug and filled with water. The water stayed cold and ice melted some but was still in the cup after 2 days. Hot liquids stayed hot about 3 1/2 hours then stayed warm til the drink was finished. This is a really good cup for me and fits in my car cup holders.

I bought this for my stepmom who is a RN. She absolutely loved it, it keeps her beverages cold or warm as is for her whole shift. If you're looking for a gift for someone that drinks a lot of water during the day and likes it cold I highly recommend this. It's just as good as any other expensive brand out there but this is more cost efficient for someone that can't or doesn't want or need to spend a lot on a cup that does the exact same thing as other thermal cups.

GET THIS CUP!!
It looks just like the picture! The colors are just what I wanted! The cup is large too so it holds a lot of drink! The lid holds so tight so nothing spills out. I love that it comes with two different straws a metal and plastic one so you can choose which one you prefer. I also like that it comes with a straw cleaner, because it's always been hard to clean my straws!

This is probably the best stainless insulated travel mug deal out there at the $20 price I bought it for. I have a Yeti 30 oz that I love for taking coffee to work because it holds a lot more than I'll usually drink and keeps it hot as long as I want coffee during the day. I bought this specifically for taking a larger cold drink with some ice to have a cold drink at all times during the day, and it's perfect for that (though I'm certain it's just as good for hot as the Yeti). It comes with a plastic straw, a metal straw with silicone tips for each end (one for comfortable mouth-feel and the other for alleviating noise from the metal on the bottom inside the mug), a straw-cleaning brush and a carrying bag for those accessories. Leak-proof aspects of this item's lid greatly diminished when using the straw through the lid opening, but knockovers are still MUCH less dramatic than with other types of lids/seals!

The most endearing feature of this mug is the fact that its lid SCREWS ON! It has a very nice silicone seal that snugly positions the pour spout/straw hole in whichever position you wish to have it (for left-handed or right-handed use). This is watertight, even turning it over and shaking it... I mean, there's literally no way it will leak accidentally. My Yeti fits deep enough in a side pocket of my backpack for the trip to work that I don't worry about it falling out when the zippers slide a little and even then it has fallen on the ground a couple times; this is too tall to fit in the side pocket and I was worried about laying it sideways in the top compartment of the pack due to possible leakage. NO WORRIES there, it DOESN'T LEAK!

A tie for favorite feature of this mug is its ability to hold the contents at a temp cold enough that, with about 1/3 filled with ice and filled to the top with cold tea from the fridge, it still had ice in it ELEVEN hours after filling it. And that was with drinking from it throughout the day, not just filling and sealing it as it seems some do to get their claims of temp retention.

My next favorite part of this mug is the capacity; so many claim 30 or 40 oz capacity only for it to actually be less than that, or it's measured at waterline. This mug holds a SOLID 40 ounces with room for the lid to be screwed on. So for coffee, you're getting the full 40 oz. For cold beverages with ice, it depends on the amount of ice used, but it holds temp so well you don't need a lot of ice.

The color is cool, the finish seems sturdy enough so far. The silicone seals on both the lid seal and the spout seal are very nice material. The plastic lid and spout slider are nice and solid, and the handle is comfortable and seems well made.

I paid almost twice as much for my Yeti and this is BETTER. Better capacity, a handle, screw-on lid that's totally leak-proof. Temp retention is probably the same. Highly recommend this item!
