I bought a Viridian X5L-RS in December 2012 and proved to be to biggest piece of crap!! The dial was loose, and the cap/lamp would not light up unless left loose. Long story short, after a few returns at Viridian I was relieved that Streamlight, who made the red light finally came out with the green laser!!
Pros: Easy to dial in and stays there, clear and bright, dependable and weatherproof
Cons: none in my opinion
