Good workmanship, but (for me) no use

The repeater is well made and makes a rather qualitative impression. The HDMI cable can be fixed, so that here nothing can slip.

Unfortunately, the use of the repeater with me led to no improvement in the signal transmission, I had still in constant frequency disconnections - Beamer said "no signal".
Should also be mentioned that the repeater has no external power supply, the signal is therefore not actually strengthened. An improvement in the digital signal transmission is carried out by a smoothing of the signal.
At least in my case it did not work, so 2 points for good workmanship and because I can not exclude with certainty that the equipment with other equipment not perhaps work.

Meanwhile I operate the projector by the way with another HDMI cable without any connectivity issues. The cable has cost one-third of the cable previously used. I have come to the knowledge that not the price of the products plays a decisive role here probably actually helps to try out yourself and take what works eventually.
