  • Great cup! Holds ice well!
Style: 40 Oz Color: Aurora
I love, love this cup. My husband gifted it to me on Mother's Day and it has been highly used. I'm a teacher so long days with no access to ice is my work day. If I fill it up with ice in the morning and refill it with water all day it will still have ice in it when I go home. I took it camping in Florida in 90 F degree weather and it held ice for 24 hrs! That alone made it worth every penny. I've dropped it, knocked it over, knocked it off tables and nothing spilled! The screw on lid held! The little flaps around the straw mean business. Nothing leaks around the straw. I haven't tipped it completely upside down, but I would expect it to leak from the straw then because there's no valve. At work I get so many compliments on the color and it is very pretty. It will show fingerprints, but those wipe off fairly easily. Even with me being clumsy the color still looks new and hasn't changed or chipped after washing. It's a large cup, but it fits in my car cup holder and the side pocket on my work bag. It's currently my favorite cup! ... show more

  • Quality for a very good price
Style: 16 Oz Color: Cashmere Cream
I only use this one for cold drinks, but it does keep them cold for most of the day. I love the straws and the different lid options. The handle is the best part of the tumbler, it’s nice and sturdy and fits into cup holders with no problem. Since purchasing this one, I also bought one of the larger sizes and am pleased with that one as well! ... show more

Love this product holds my Water and ice for a really long time! Not sure if I use it for my coffee by you never know! 32 oz is a lot of coffee but not a lot of Water it’s main usage! Seals well and the price is fantastic a lot better than some of the famous name brand! 2 screw on leakproof lid one with a straw! Really a great value. ... show more

  • Keeps things extra hot!
Style: 16 Oz Color: Midnight Black
I gave this to my elderly mother as a gift, who is a hot tea drinker. Most of her tumblers in bought her for her tea would only keep things hot for a short time and even the knock off of "those other cups" were not doing their job, you're unable to locate replacement parts, and the lid on that cup (it wasn't tightening.) This cup came up on my feed and I thought about it for about 5 minutes before hitting the Add To Cart button. It keeps her tea extra hot for the entire trip, the twist lid for straw only use is geniusly designed... And it's even easy for me to clean because I can get my hand inside of the cup to remove any sort of stains that tea can leave. It doesn't say it's dishwasher safe, but it's just easy enough to hand wash. It's durable, as my mother has dropped the cup on the ground accidentally, and it only has a really tiny dent and two tiny scratches. (Which I inquired about a bumper/silicone boot for the 16 oz... They aren't available for it.) Outside of her Skechers, this was one of the better gifts I have given her, and I would definitely recommend this brand to anyone looking for a new cup. I definitely will be a return customer... Only other suggestion to them would be to offer a light orange cup, as I would buy sizes from 16 to 40 oz for myself.. (I also plan on another 16 oz for my mother, just as soon as she decides on a different color.) I am highly impressed, as was my mother. ... show more

  • Favorite
Style: 40 Oz Color: A Morning Mist
I absolutely love Iron Flask. I have multiple water bottles, and was thrilled when they came out with the Co-Pilot. It was my favorite cup to use, however I found the straw lid difficult to remove. And the cap from the lid came off recently revealing the foam inside! I contacted the support and they were able to send me a replacement since I was just a couple weeks shy of my one year warranty! Cutting it close! But I'll have my favorite cup back! Other than that, it holds water nice and cold, or hot! It fits perfectly in my cup holders and the handle is very handy! ... show more

  • The Yeti slayer
Style: 40 Oz Color: Dark Pine Speckle
I bought one of these (the 40z tumbler in green) because I was looking for a good insulated mug that was less expensive than the well-known brands. I've had bad luck with cheaper mugs before, but this time I hit gold. The other day, I wandered off and left my iced coffee in the back seat cupholder (ADHD be like that). I didn't check it again for a full 36 hours. When I noticed I left it, I took a sip, assuming it'd be warm and diluted. Nope! Not only was it still cold, it still had most of the ice in it!!! The build quality feels excellent, and it does something that a lot of cups like this simply can't pull off: The flip lid is both easy to open and close AND totally leakproof. Usually you get one or the other, but not both. Needless to say, after this I bought an Ironflask insulated water bottle for my workouts. ... show more

  • Keeps my drinks cold for a long time.
Style: 32 Oz Color: Twilight Blue
It keeps my drinks quite cold for a long time. I can put ice tea in the cup in the afternoon and it will still be reasonable cold in the morning. It barely spills when I drop it and it doesn’t break (Hey, I’m clumsy, OK?). My only gripes are that it looks kinda platicky, which it is, and there is this 1” square logo situated so that every time a right handed person picks it up to take a drink, they bring that gold logo towards their face. Personally, I think it belongs on the other side of the cup. There is another logo that says “Iron Flask” running perpendicular from the base that looks nice and doesn’t bother me. ... show more
