Good design, poor loading performance

This thing looks great and it's a bit ago on the desk. In fact, it works well ... basically.
Now I must admit that I have not used the device with a Nokia phone, but with a Nexus 4. This is apparently not ... the charging power is so bad that after one night only 20% of the battery were charged ... well that may be because my Nexus 4 is in a TPU casing and the charging performance of the additional distance of about 1.5 mm is impaired from the phone to the loading platform. I did not try to remove the shell before, because I do not want to make before each loading cycle the ... there is much less effort to use the charging cable. The Qi technology seems to me a total of not very mature yet, because I have been able to charge the battery in one night to 100%, with the cable it comes within about four hours!
Overall, I can not tell you how the device works with a Nokia phone, but the Nexus 4, it seems useless. Since it still works in principle and it also has a beautiful design, still just three points. I sent the unit the way back. Price and Porto were replaced without difficulty.
