I own a BrightStar laser, by Laser Star, with nearly 600 hours on
it, and I had well over 500 hours on an older pre pulse shaping Laser
Star at my previous job. The only problem we ever had was on that
first laser, and that was due solely to poor maintenance, and was
corrected. As far as I know that shop is still using this laser
without problems, although it has been @5 years since I moved on.
I have set the laser up beside my work bench, so I can turn in my
chair to use it, without having to change stations. After all these
years I would be lost without the laser, it is such a part of my
techniques now. Assembly, repair, etc. Even work i will complete
with the torch is often pre tacked lightly with the laser, instead
of parts being held by clamps orthird hands.
