The biggest thing I’ve noticed with these bottles is less condensation. However if you are rough on them, you may have issues with water leaking into the in between area.

Five stars! This bottle is a game-changer. The insulation keeps my water cold for hours, the bite valve is a perfect no-spill solution, and it's incredibly durable. I take it everywhere!

Durability good. Insulation awesome. Portability awesome. Leak-proof excellent. Cleaning performance is amazing. I recommend this very much good.
