The design is very subtle but it looks very cute and the bottle is due to their shape very well in hand. One does not feel that she would one fall, when handled, out of his hand.
The best we like the vacuum cleaner itself. This is shaped like a nipple and thus gives the baby the feeling to be at Mama's breast.
In closed condition, the bottle is around tight and even with vigorous shaking drips nothing.
Conclusion:
Great bottle to the Mama involve some time out to bring and dad with.
