I have one, it is great. The focus ring is not as tight as I would like, but the output is quite good. I don't have a laser meter but I can tell it's quite a bit better than the 200mW red new style laser. The new 300mW red burns faster and I did a test. The 300mW laser will burn through a CD case in 3.5 seconds focused to a point. The new style 200mW will burn through the CD in 6 seconds, twice as slow. Since the red light is deep red, the brightness between the two is not noticeable to just slightly noticeable. So, yes it is worth it, it was for me.
