Bought this to replace an streamlight e2dL and I can't be happier. It's brighter, just as tough, and the clip is much easier to remove for weapon mounting. The only downside is the non intuitive user interface that involves twisting and clicking.
Pros: extremely bright, well built
Cons: programming the light settings is a hassle
