Edit of 21/12/14: After exchange (fast, thank you Amazon ...), received new housing. After a little over a month of operation, nothing to report except the blue LED that has worked more quickly, but it is a lesser evil because it illuminates much as a flashlight ...
I joined some reviews: Warning not to use it to keep changing the disc inside, without trying, I think that after 10 assembly / disassembly threads will be at the end ... and if the screws are lost before :)
