However, the Produnkt gets a star deduction, because I find no matching 2-fold frame. I have under the light switch (like many others) have a grounded outlet, and had "2-way Kopp 308502080 Paris Cover" bought for this product are the 2-fold frame. But between dimmer and frame is an ugly gap of 0.7 to 1 cm which looks totally stupid. So if anyone knows a 2-gang frame which closes completely, I would be very happy and I would Amazon / seller ask without delay in the product description to link.
I can not connect to previous speakers: no defect, no sloping or loose plate, installation after switching Read the manual totally just (who are not familiar with electrical installation, should anyway leave it alone!)
Conclusion: price / performance absolutely unbeatable, frame or accessories expandable, yet my buy recommendation!
