Well these two are great lasers. My new twins. I am not going to write much of a review. TEM00 on both, nice tight beams and good divergence. Great power output. The 589nm IS noticably more yellow than 593nm, see picture for comparison.
Damn MAn that looks very nice!!! Hopefully I will own such a beautiful 589nm portable in the future.. You should post some more beam shots when you get some time..
