I used the Line6 G30 for over 10 years. I still have it, but lately I don't need a pedalboard for most of what I do, so bringing the additional power supply etc felt a bit clumsy. I recently got a Lekato WS-90 set, which uses the 5.8GHz band and presumably more resistant to interference. It may still be early days but it just works fine and charges quickly (USB, which we always have available on several of our extension units).
The only drawback, perhaps, is that it's the type that plugs in directly on the bass. I don't like that. So I do what I was doing with the Line6 already: a small 40-50cm M-F cable from the bass to the wireless transmitter, then the transmitter in my pocket or in a holder on my strap.
