Although still working and only being 2 1/2 years old, my Xvive U2 has seen better days.
Having a search on the Amazon brings up a plethora of cheap alternatives (rechargeable wireless systems) for under £50, with names I've never heard of such as:
Getaria; Muslady; Ammoon; Lekato.
Does anyone know anything about these 'brands'? There don't seem to be reviews anywhere other than Amazon.
I would splash the cash and go for a Boss WL-20, but apparently they don't work so well near wifi.
