Unfortunately turned to nem half year a loose connection in a cable, despite fixed installation and therefore virtually no movement. Given the otherwise consistently good reviews here I would very strongly suggest a sunday product. But with the price also not a big surprise.
Large But: The seller (here Perfect HD) has reacted very quickly to my return request and offered me a free replacement (after half a year!); eh I knew it was about the new cable in the mailbox. Very high praise for it!
Conclusion: had some bad luck, but extremely kollanten seller caught, on the whole, so very happy. 4.5 stars with tendency to rounding.
