Static electricity

My little chip of three months was very interested in this toy during his visits to the pediatrician or waking workshop and that is why I decided to buy the same, the same brand.
I was happy to see him get home faster than originally planned, but at its first use the balls have already started to stick against the walls and you have to shake the tree loudly several times they descend. No problem when my baby will grow and will have fun shake in all directions but for now it is rather painful. Also the walls seem quite fragile because they do not appear to be welded together but rather interlocked to do so precisely when a child acquires more force.
I hesitate to return it from Amazon because they do not guarantee the repayment in full, it must first decide whether there is impossibility to use it as is ... For the price, gamble
