The machine cannot run for more than 1 hour before stopping due to high temperature. It is not intended for professional work as shown in the factory videos, but rather for very small jobs of a few minutes maximum on surfaces of a few cm². The lenses burn very quickly, and with the 5 lenses provided, you can work for up to 5 hours before the machine becomes unusable. So you pay for a machine that you will receive 3 months later and you can work for a maximum of 5 hours before it is unusable. Even when buying new lenses, I really doubt the lifespan of the machine seeing how quickly the pieces have to be replaced.

Excellent 👍
