I am using this bottle for the first time today at work. I wanted a metal water bottle and insulated because I'm not a fan of ice and I don't want a bunch of condensation. I poured cold water from my fridge in it this morning with a couple squirts of lemon juice. It's been 5 hours and the water, without ice in it, is still as cold as it was when I took it out of the fridge. There has been no condensation nor does the bottle even feel cold on the outside. I like the handle on the lid for easy carrying and the neat little bag that comes with it is great for that, too. I ordered the solid red 40 oz bottle. I had to use a long handled sponge to get down to the bottom to wash it. I'll have to see if I can find one with a longer handle because mine barely reaches the bottom.Update 5 months later: I still love this bottle. It travels with me to work every day and there is not a scratch on it. I haven't dropped it and not in the habit of banging it against anything either. It keeps my water ice cold for the entire work day and beyond. I sometimes use it at night at home and the water is still ice cold in the morning. I highly recommend the flip and sip stein lid. I like that much better than the lid that came with the bottle. Both bottle and lid are easy to clean. I only put water with some lemon juice in mine. I handwash with soapy hot water (bought a long handled silicon brush just for the bottle) and let air dry. I haven't seen any rust in the bottle. I also haven't had any issues with mold anywhere on the lid. This has really helped me increase my daily water intake.Update 7/15/21: I dropped my 40 oz bottle onto the concrete garage floor and it wrinkled the metal in such a way to create a sharp edge. So I ordered a new bottle. I was sad to see the 40 oz size wasn’t available but the 32 oz does fine and I love the hombre coloring.
