FBF provides a fast and efficient rental service, even if you do not live in Germany. I give them my highest recommendation and would definitely use their service again.
I hired a 35mm slide scanner in the UK. It was shipped to me quickly from Germany, with excellent instructions and everything I needed to get started, including a UK power adapter! The scanner was easy to use and produced excellent results. Returning the device was very easy too: just drop it at the post office and use the pre-paid mailing label.
The whole experience was very positive. The cost was also cheaper than sending my slides to a lab but with the same high-quality results.
10/10 for efficiency, quality, service and price. Highly recommended.
