The HDMI switcher came very fast with delivery via Amazon and worked very well for my first test. When I tried to use the device a week later again, neither the remote control nor the button went on the device. Moreover, now I have every few seconds very annoying glitches and interference.
I have a part now sent back. Unfortunately, I no replacement was offered, but only one credit (probably because the equipment is now 5 more expensive than I bought it).
I have yet again bought the device (as warehouse deal) and will see if I just had bad luck the first unit easy.
I will customize these review then accordingly. So far, I can not rate with 1 star device.
EDIT: My second device is now connected and working so far very good. The problem with the remote control I've had the same again. The reason for this seems to be easy, that the source you can select only when it transmits a signal. Somehow, the switch does not seem to be but kompartibel with my Denon amplifier, because one can never choose a source, hence my confusion at the first device.
Image and sound errors I have no far. Wait wirs times;) If I write nothing here, then everything must be okay with the device.
