My first ever wireless system seems to work just fine.
It's the x Vive U2 or something like that.
It came bundled with my Jem jr so I don't really have any thoughts or experience other then I plugged it in and it did the things. So not bad.
I tend to sit in classical style with my guitars so I was conscious of it's positioning but really wasn't that big on an issue.
It bends to just about anything from 0 to 90 degrees and has a little rubber foot on it so it will not scratch up your guitar.
