I am very satisfied! I had lost it and bought it again. Its material is very good. The lid closes perfectly, so it doesn't leak a drop even if you have it loose in your bag (it won't open by itself). I had it for a year and the only thing that happened was that the color on the lid faded a little because the sun was hitting it when I was on my bike. I have it with me every day, all day, at work and during workouts. The amount of water is very satisfying for me because it's enough for the longest part of the day (of course, I will refill it at some point), but at the same time, it's not too heavy. Also, when I would take protein supplements, the powder would dissolve very well with the mesh it has. Finally, the bottom compartment was very convenient for me to drink water during my workout, and when the workout was over, I would refill it with water and add the protein inside to drink it immediately if I wanted to.
