The socket is now for two months in operation. The cover I as described always washed by hand with a sponge. Nevertheless, the subject is now going through the transport in the Kiga bag down already in some places and there are top Krazter. I am really disappointed. One can indeed calculate how the subject in six months looks ... The pressure is what makes the can for children and I think it's really a shame if he does not even hold a few months! Otherwise, the can top.
