That are not laser hosts, these are fully working lasers.. A DIY Assembly of laser parts where you just have to put use to the module/heatsink.
This guys name is Rick Trent and he has been on the forums lately, with a little-to-no knowledge about lasers he seems to be doing quite good..
Some of his products are overly exaggerated but all in all he does good at what he's doing so far.. And he's legit (kind of) so , good thread .. :thanks: for letting us know!!
Also please make sure you do a little search by using the "Search" option, of the forums before posting a new thread as there has been a gazillion times of redundant information, i would rather not see a good thread be burried under lots of redundant threads.. Just saying!
