Xvive Wireless System U2 Black Gitarren-System

I use the radio link in the rehearsal room so I don't keep tripping over the cable. The fact that there are plenty of other tripping hazards lying around is another story.
The operation is very simple, after I had deciphered the microprint instructions for setting the radio channel with a magnifying glass.
For my Yamaha RBX A-2 bass, the transmitter jack seems to be a bit too long, When fully inserted, no signal comes through. I solved the problem with a small distance ring (approx. 1mm). Despite this construction the transmitter sits amazingly firmly in the socket. For a LIve gig, however, I would not risk it.
In various guitars of the band (Shecter, Indie, Fender, Hagström) the transmitter fits also without distance ring.
The receiver is in the input of the Tretminen ind disturbs there no further.
There is no noise or crackling in the sound transmission. Soundwise I cannot determine any difference to a cable. There is also no noticeable latency.
I am a bit suspicious of the folding mechanism between the plug and the electronics housing. Currently you have to overcome some resistance to adjust the angle - and that's a good thing. Time will tell if it stays that way or if the whole thing starts to rattle.
The slide switches do not make a very valuable impression and are too smooth for me. I have already accidentally switched the transmitter on or off several times just by touching it.

Conclusion: sound-technically nothing to complain about, mechanically it could be a little better processed.
For the price quite all right.
