The Core 150 Bottle offers by unscrewing the lid a very convenient option of filling and cleaning. The 3 serving boxes are still a nice extra feature, but I do not use. For the core 150 is used in each workout (4 x per week). Contents are a BCAA and carbohydrate powder, dissolved in water, so very thin. And with this very fluid content seems the core 150 so as to have their problems because with time, a thin liquid film between cup and screw-cover forms. It runs but will not start, so it's a bit damp in the area. Presumably the reason happens because no rubber seal between cup and lid is present and therefore applies to all bottles. As I fill the bottle until Fittnessstudio with water, this shortcoming is for my use not so tragic and I have an Exchange dispensed with that very reason because it can not be better without rubber seal. My core 150 fits perfectly and is not damaged so that can not be the reason.
In summary:
- Good water bottle with a lot of capacity (1 liter)
- Very easy filling and cleaning because the lid can be abgeschaubt
- Including Portion boxes
- Not 100% leak-proof (running between cup and lid - it forms a thin liquid film)
