For $220??? Wow, that's expensive and I keep hearing bad things about that company! If you want a 1.5W--1.8W blue laser that's focusable, you can get one from Sci Fi Lasers (see banner ad in the top middle of your screen) for $100, and it's from a reputable company. I have one coming in the mail right now. There are plenty of reviews of it in the reviews section of this site. It's the SF501B laser.
