The 2AA MagLED I've owned has been great. I bought a set of them at Wal-Mart about 2 years ago and kept the one with better tint. I even upgraded the stock thin plastic lens to a thicker glass one.

It's a simple bomb-proof design - with all the multi-stage clickclickclick lights out there, it's nice to have a single stage LED that is well-suited to many tasks. It's a good combination of brightness, runtime, and cost-efficiency.
