So far so great

This is my first laser tube replacement and I am blown away by the difference between this and the initial cheap Chinese garbage I had initially. I'd recommend anyone getting a K40 just buy this while you're buying your machine and you'll have an excellent backup tube to use as soon as the stock one kills itself. It went in with no issues and the first thing I cut (didn't even end up needing a mirror alignment thank God) was 1/4" MDF. The first tube that came stock with my machine could handle it in 3 passes. This new tube from Light Object cut all the way through in one. Couldn't be happier with my purchase or the professional way it was safely packaged. Thanks, Light Object, you are now my go to for laser parts supply. :)
