Good Bottle, which impresses with its appearance

The Mizu Bottle I have, what other criteria should also have chosen the one hand because of the material, on the other hand due to the design and size. Preliminary one should note: the bottle is suitable only for cold drinks.

positive:
- Mizu offers many sizes, so I could choose my optimum capacity
- Pretty design (I think I was never so often addressed to a Bottle)
- Light material, not plastic
- Upper is after three months minimally scratched (despite challenging environment handbag)
- Does not leak

negative:
- The shutter opening is for me a little too big (I spend a lot of time in transport, in unfavorable Ruckelmomenten I have my drink on the shirt, cobblestone is most likely in any case during the journey not the best drinking environment). For the cleaning, however, the opening is optimal.
- Washing-designed, without dishwasher, a little hard. On the one hand this is due to the special shape of the lid, on the other hand is between the outlet protective rubber and the screw cap is a small gap, to which one rankommt difficult
- Has somewhat deformed (I think she fell off me) the soil has minimal curved outward, so that the bottle still stands, but when filling wobbles slightly
