Iron Flask Sports Water Bottle - 18 Oz, 3 Lids (Straw Lid), Vacuum Insulated Stainless Steel, Hot Cold, Modern Double Walled, Simple Thermo Mug, Hydro Metal Canteen (Blue)

Bought 3 of these for holiday ( different sizes) and they were 100% worth it. Kept drinks lovely and cold in 40°c heat. I've not tried a hot drink so I can't comment. I even take the bottle to bed every night with 3 ice cubes in it and even though the ice has melted its still so cold in the morning. I would 100% recommend

The water bottle is actually so much nicer than I expected. When I first opened it I washed it by hand like it said that filled it with ice and water, I only took a few drinks and forgot about it and left the house for about 4 or 5 hours and when I got back the ice wasn’t melted yet. It really surprised me but after that I had to leave the house again for another 3 hours and once I got back sure the ice was gone but it was still super cold. The only thing I can complain about is that you have to hand wash it but honestly that’s just me being lazy. I really like this water bottle for the price it’s definitely worth it. I bought the 18 oz because I wanted it to be small enough to fit in my cup holder and not get in the way of anything. I would 10/10 recommend this water bottle to anyone in the market for one.

Keeps things cold but it leaks when it’s full

This bottle is exactly the size I needed and it came with three different lids which was great. I haven't used all three to test how leakproof they are, but the one I've been using (w/o the straw or opening) has been very secure. Unfortunately, there was damage - an indent at the bottom and a squished edge. So far, it doesn't seem to affect the temperature control, so I decided to keep it anyway.

I definitely love this product
