A little disappointed when this arrived in the mail, it is good quality as it is made of metal, well the bottom half is, the top half is made of plastic, the sound doesn't really sound like the sonic screw driver at all, and the light can barely be seen. As for the screw driver part, the heads are stored in the plastic part of the screw driver, and they are difficult to remove from the storage area, when you have finally managed to get the screw bit that you need, and place it into the end, it bulky to use, and it slips. Also the screw bits are coated in green paint, which scrapes off as soon as you start to use them.
