This has two disadvantages:
1. Visible Fingerprints remain in any use on the device back - the problem is not quite as bad as the black / blue New 3DS XL models, but a significant deterioration compared with the standard trim that came with the device, in which this problem thanks to the matt surface does not occur.
2. The surface is significantly more slippery and uncomfortable than the standard trim. At the top of that does not matter, at the bottom it leads but to the fact that the device can be summed poor stable, and thereby simply bad / unpleasant to the touch.
In addition, the material is somewhat less stable than the simple standard trim. This is the bottom always minimal after - presumably this is only half a millimeter to a millimeter, but you always feel that you can easily pushing the trim strip when holding.
