power supply and laser tube are both Vevor branded. I know the power supply is a standard power supply, it changes brand often but the electronic is always the same.
the laser tube aesthetically seems well made and very similar to tubes from other brands. the technology is described in the notes and is the same as many other more expensive brands. I spent little money, so I will be happy if the real power is as declared and if the life time of the laser is at least 1000/1500 hours.
