Query: Lasted less than a year

I bought this item 01/05/10. It started having problems charging a few months ago, but with some jiggling, the adapter would eventually charge my laptop. This is my back-up charger at home, I use a separate one at work. I probably would have written a review earlier if it was my main charger, and gotten a replacement one even sooner. I just bought a new one today, at 1/3 of the price on ebay and a 3 year warranty. Do not buy this charger here!
