I'm looking to get a green laser that's smaller than the standard PL-E Pro, so i'm looking at the PL-E Mini in 700mW 532nm or 1W 520nm. However, i'm also looking into Sanwu's stuff for the first time since I hear it's a good company and the Challenger 2 seems like a good pick as well. The main thing i'm wondering is how the models compare in terms of size, battery life, and heat. Any info?
