I had bad luck or is the transmitter scrap?

For me, the transmitter has only once to work, no longer.
The support has stalled me and repeatedly asked pointless questions that had already been settled in my description of the fault by e-mail.
At the end of me but the transmitter was refunded. After all.
The transmitter has an overall very fragile impression, the cable is very thin and short, the button for activation is difficult to make ....
I would say that man can save buying.
