Look, engineer the thing to stand up to normal use. Way more reasonable than trying to get everyone the world over to baby their chargers.

I go through about one of these chargers a year. I leave one at my desk at home, so I don't have to move it, and I take the other one with me on the road. The one I travel with gets plugged and unplugged probably 5 times a day... and it never lasts more than 6-8 months. Shitty design.
