Query: Buyer beware-buy the replacement warranty

Against my better judgement (read the negative reviews) I bought this camera for my 18 year old son. He used it a few short months and now the lens won't retract despite the sounds that the camera is trying to do so. Consequently, he can't turn it off without taking out the batteries. AAAAnd he gets a blank black or white screen and can't take pictures. Spend a little extra to buy the replacement warranty. I wish I had.
