Why so hard?

We all have electronic items that require batteries. Some are completely innocent, others not so. Last night I had to replace the batteries in my heater/aircon unit remote and having purchased some during the day I went to work. As usual through, this seemingly simple task, turns into mission impossible as you try to free the little metal cylinders from their plastic and cardboard prison.

I know the manufacturers and shop keepers don’t want these items being stolen, but is it really necessary to make it harder to open this packet than a bottle of childproofed painkillers?

It seems that no matter how many perforations they put in the cardboard, they only go half way through which means you end up with a tiny pile of hairy cardboard before you break a nail, and then, finally, the batteries fly across the room, because you are pushing and pulling so hard you loss all control.
