For product itself:
Positive to mention is:
+ Very elegant appearance
+ Very handy
To install and remove the device + Easy
Blocks are + way fit, no holes (unlike the previous speakers I can not confirm the heavier pin removal)
Negative unfortunately:
- Very strong plastic smell, which settles after a short time also on his fingers.
- Not ideal used together with the silicone sleeve of Mumbi, since the cover makes the phone thicker minimal. What the shell no longer makes a perfect fit. (Not therefore significant since it makes little sense to use this cover together with a back cover)
- NFC chip is missing! The built-in chip which cover normal "Near Field Communication" makes possible missing! - Was not mentioned in the description.
Originally I have this BackCover ordered in addition to an aluminum bumpers, I'm curious if this then now fit, then I would probably use the Smartphone in 2 versions, with aluminum bumper and the leather cover and without NFC, or when NFC more uses receives such Cashless Bazahlen at each checkout, with normal cover and silicone sheath.
Currently the lack of NFC chip does not fall all too much negative aspect because I had this only requires initial setup with my Sony SmartWatch 2 (but would also alternatively)
Perhaps it is also a retrofit NFC capable battery, as it looks to the effect, I can not say unfortunately.
Once the aluminum Bumper has arrived I will report more so, however, only 4 stars.
