unpacking I hesitated to open the device and insert the batteries: should remove the "cap" or plastic (plastoc) opens it 2 t (drag) ?? eventually must be removed "cork" The really seeming frail plastic and the plug being hard to remove the first time, I really was afraid to break everything. After that my main regret is that the rod we can not tear (metal) plastic to go in the dishwasher ... will not forget to rinse directly after use if not a lot of fun .... I ' hope it will last a little though ...
