Do not have any experience of the one you point too.
Do try to get a good test before you buy if you can.
Bought a Cibox 9" job from PC World. My comments would be that it does what it says on the box.
However, the resolution was such that when viewed up close it was very pixilated and not clear at all. Viewed from six feet or so away the picture appeared as just a blob with little definition.
All in all I was very disappointed and it has been packed away and relegated to the attic. I would be very careful as to what I purchased in future. Not sure that many of them have the resolution to do the job properly.
I do have other framed A4 size photos hanging on the wall and the frame could not even approach that quality.
I have not looked at any other types so cannot say that they would all be similar.
