I have had plenty experience with C02 lasers. These lasers are glass tube lasers and the life on them are suppose to be 1500 hours. You would be lucky to get a 150 hours out of them. Glass tube lasers are not efficient at all. I owned one myself and sld dozens of them. Now I ran my Epilog Legend 36EXT 60 watt, which use a sealed Coherent C02 tube also known as a RF laser tube. I love it.
