Plastic AixiZ Line Lens for 12x30mm casings 120 degree

For the price I shouldn't complain. They do put out a line and it is focusable. The line is segmented especially at the ends. The line is not very focused, but what do you expect for the price. I am using this to indicate a stopping point where an inch isn't a big deal, so they are just fine. Getting the plastic lens in can be a bear (Flat side goes towards laser). You need to have a pretty hefty 20-30 ma output to get a good visible line.

lens fell out of holder. actually it was never apparently affixed in any way. maybe this is normal, but i doubt it. cheap though, but not usable for me.
