This is one flaw in apple's products. Their magsafe adapter for the macbook pro does not last long. The original adapter that I had for my MBP 13 lasted only for almost a year and a half. Almost the same time as last year. I bought a replacement from Ebay that cost me $29. I know it's refurbished so I just decided to buy an original one from ebay as well. It cost me around $58. After a year. The power adapter/charger broke down. I've decided to buy a replacement charger on ebay. I don't want to spend more money on a power adapter. Are you guys having problems with your magsafe power adapter also?
