The image quality of the Rollei is absolutely fine. However, optimal brightness and luminosity of the images is exactly forward forward only available for viewing. Even at slightly offset viewing angle, the image becomes dull and loses extreme luminosity.
This I have seen much better in picture frames eg from Sony.
The images change can be provided with various image effects. The effect, however, iris go but not liquid, but with striking jerking of equip. Also this feature a bit disappointed.
In addition to viewing photos and playing videos or the accompaniment of the photos shown with background music is possible.
Wonder at the sound quality can not be expected Allerding at the small speakers.
Overall, obtained with the Rollei 9100 Pictureline a picture frame that does what it should. This low viewing angle for optimal image quality is a nuisance.
Therefore, there is of me, unfortunately only 3 stars.
