Toys with low quality

I've ordered this device with the expectation to accept some loss of quality. For so little money you can not ask the quality of an outrageously expensive film scanner simply because it is so is no scanner but a Fotografiermaschine ".
The equipment has been tested exclusively with slides, because I bought it for.
Since I could satisfy in any way the results, I returned it the next day again to Amazon.
If you do not have high demands on the quality and simply want to digitize only his slides (because they are otherwise no longer gets to see) reaches the device.

PRO:
* Operation is simple, you can not go wrong
* During the scanning process no PC required - Standalone operation
* Works fast, although you can load only 3 slides in the holder.
* If no extreme contrasts occur (no sky, sunlit surfaces) are the results acceptable

CONTRA:
* Photos are especially in the light areas (sky, bright surfaces) overexposed - here there is no possibility of scanning to adjust the exposure - for me a no-go!
* Each phone has a more intelligent exposure control
* On the side is the left and right about 1mm cut off (when you consider that even the frame crops the original, the loss of image information sums) - for me a no-go!
* Even if I aligned the slides in advance above and the device inclined backwards - is occasionally seen at the top of a narrow strip of shadow of the frame and the result needs to be further curtailed.
* The blue color cast, can be used in the processing remove, but why is not the same as a neutral light source fitted with natural light, and the exposure is adjusted according to the device?
