Iron Flask Insulated Mug
Love my insulated mug! I primarily use it for water purposes. It keeps my water (without ice) cold for hours. It’s a sturdy mug and the color is vibrant. I’ve turned the mug over a few times and it does not leak. Easy to clean. It’s high quality and it came with 2 straws and 2 different lids. Don’t hesitate, buy it now.

Get it! Better than some other tumblers I've used- including a Yeti
AMAZING CUP!!!! With ice, my drinks stay cold at least 24 hrs- I have the rings of ice for inside large tumblers and the biggest is almost always still in there the next night when I refresh it. Without ice but with cold drinks, 12-14 hours still cold, by 24 it's still cold, but not like it was fresh. Don't know about hot liquids yet since I mainly use it for work to drink water, but also use it out and about to. I've gotten lots of compliments on the color, and have told people where to find it. It has also lasted longer than other brand cups I have had when accidently dropped. It finally got tested last week when it fell from about 5' high and hit the hard floor. The only damage I saw was a small dent, but it didn't spill water everywhere, I use the straw style lid. It wasn't until I refilled it last night before work I noticed the lid was cracked and it wasn't closing the normal way. I reached out to their customer service and they are taking care of it and are absolutely amazing. All in all, it feels great in your hand and fits in the cup holder in your vehicle, and keeps your drinks cold if you prefer ice cold drinks!

These thermal cups are fabulous!
This is my second purchase. I also have a green one. I love them. I take them to work with me everyday. I plan on using them for years to come. I want to get another one in another color. I soak the lids in denture tabs because the rubber around the straw area does not come out to be cleaned or I soak them in bleach. That is the only thing that I do not love about these cups. Everything else is exceptional. Easy to clean. They come with 2 straws and two different types of lids but I particularly use the one with the straw in it. I fill them with ice at work on a Friday and I still have ice in them when I go back to work on a Sunday night. That's how great they are at keeping your beverages cold.

Good for regular use.
I got this to help keep my Mom hydrated. It keeps things cold for a long time. Easy to use and drink from. Has been knocked over by unsteady hands. The straw lid does leak when tipped over. The flip lid broke when it fell over. I was hoping the color would be brighter than it turned out to be. The purple one is very nice. The blue one is blander and darker. Not really a dark teal on the screen. I have other iron flask bottles that work really well, and don't leak. I like that they come with a variety of lids too. Very economical for the purchaser. This is a good contender for other popular brands, but I don't like that the straw lid leaks.

Daily Use for Over a Year: Airtight & Ice Cold
Im getting ready to send another link to this cup out when I noticed it's a frequently returned item. I'm not sure why. Ive used it near every day for over a year now and I've had no problems. It is leaking proof, trust me I've dropped and knocked it over a lot, sturdy - see above - and will keep my drinks cold and the ice solid drinkable overnight and into the next.

It does what it says its able to do
It kept ice for over 24hrs! I do wish it came with a carrier pouch, straw caps and cleaner brush💬 But other than that I'm in love 💟 with it and will not be returning it. It's also very attractive too😍
