IRON °FLASKClassic Tumbler - 710 ml, Vacuum Insulated Stainless Steel, Hot Cold, Double Walled, Thermo Travel Mug, Water Metal Canteen (Calacatta)

I bought this because I wanted to start making my own drinks to take to work instead of buying everyday. I work in a busy kitchen so I needed something that insulated well and kept the drink cold long enough for "in-between" tasks sips. I first used it when I was home and put ice with my drink. I fell asleep and completely forgot about it. About three hours or so later I woke up and the ice hadn't even melted and the drink was still REALLY cold. I was shocked considering it didn't have the top on it. Then again the next day I poured coke and ice into it and feel asleep. Must've been around 11pm and I woke up at 4 am to find that the ice hadn't melted( again, the top was off). Then I picked it up with the ice and coke still in it and said I was going to wash it at work. I forgot it in my locker and 8 hours later....THE ICE HADN'T MELTED!!. I ordered the bottle version of it as well because this worked so well. So if you're looking for a good insulated cup/bottle... this is the brand/type to buy. Not to mention it is easy to clean. It's not leak proof as the top has an opening you can't cover or close...but I bought the bottle for this reason as well.

The quality of this product is disappointing. It’s also frustrating that it does not come with a sealable lid. It doesn’t look like you can purchase a sealable lid either.

When they say hand wash only, they mean it. I regret the choice to put this into the dishwasher, because I love this mug! Ice lasts nearly as long in this mug, as my Yeti. Easy to grip with my smaller hand size, as well. Please HAND WASH ONLY!

This cup does exactly what it’s supposed to do! I literally left ice in the cup from the noon time when I had my iced coffee to overnight I forgot about it and when I went to clean the cup the next morning the ice was still very much there?m! Drinking from the stainless steel straw is perfect on a hot summers day! I think it’s a great buy!

I have been using this product for sometime now and no complains at all.
