I bought my vls 4.60 from Universal in 2009, the first tube was bad, but they sent a replacement as soon as we determined the problem. That tube just went out. I talked to my rep, Sue Stull - Midwest Laser, and she got to Universal. The warranty expired in July of this year, but the company went ahead and honored it anyway. They will be sending a new tube out today.
What great people, and a great company. Thanks Sue and Universal.
