Query: I had to get it

I really only got it because I had no other choice. When it's working right, its fine; with good life and a handy indicator on the back to check power level. However, my first one went south after only 15 months, and now won't hold a charge for any significant amount of time. I now have three of these (including the original, which is good for like 30 minutes) to make sure I get the time I need on the computer. The power source went south not long after.
