Hi there!

As you may have noticed is free-of-charge and there is no plan to change that at the moment.

However, financially it's not an effortless operation, of course. The costs include ...

  • rental fees for multiple webservers
  • rental fees for photo equipment and shipping costs
  • about 20% of the tested equipment is actually purchased in normal shops out there. We've only minimal relationships with a few manufacturers.
  • testing equipment (studio equipment, charts, software, hardware, etc. pp)
... and, of course, it takes about 2-3 days of effort to create a review.
