Property since the bottle since 2 weeks in use and am thrilled. Easy to clean due to the wide mouths and fill. The shutter can be opened with one hand (for children may be a bit too heavy), and notice to the rear. Practically, in order to prevent accidental opening of the closure in bags / backpacks also the metal bracket. Overall a really good daily companion. The wide-necked lid fits übrigends on 1L wide-mouth bottle Nalgene, whom the 0.7L would not be enough ...
