Who buys cheap, buys twice 1 3

As can be seen already from the title, I can only say that the button cells are not fit much. They have in a toy caterpillar that plays music, held just two days. The original button cells, however, have held three weeks that with the same strain. Perhaps our blister was from a "mon production" or stored easily even too long? Anyway, we were not satisfied and do not recommend the purchase.
