Little use is already precisely matched to the mobile without any protective sleeve, the slightly larger for unspecified cover. It would be nice to note here in the product description, to which (additional) total thickness, including cover the station remains usable.
I tried two covers:
Terrapin Rubberized Hardskin Cover for Sony Xperia Z2 (very thin)
and
mumbi X TPU Cases Sony Xperia Z2 shell (slightly thicker than the former but in my view still thin)
both at first did not fit into the larger application (the little one is always excluded, see above).
However, the use of plastic is very soft and the Terrapin shell fitted only just so not into it, so I have to work with a cutter knife just scraped a little (duration about 10 minutes, you will not be cut so ;-). Well past into at least the thinner shell including mobile and it is loaded.
The supplied cable is significantly longer than similar products of the competition and thus more usable, the station itself significantly smaller. One-handed operation possible (with slight dislocations). A heavier station would be nice but overall, so you can take with one hand the phone without contortion hand.
Since the station is significantly more expensive than almost equivalent products of competitors, and the use has yet to be processed I had to give in consideration of the long cable (real plus) 3 stars. If the application would be usable without processing, it would also become four.
