This has transformed our playing. No messing around with stage monitors, no more feedback nightmares, less hearing loss(!) a lot more room in the van, and we have a different mix to the audience, so we stay on the money. Batteries last well and there are enough functions on the unit to tweak the sound to how you like it. In the studio we can now rehearse long into the night, (where we use headpones). We tried another systen that shall remain nameless, and did nit like it. Thomann actually recomended this when we phoned up, and as it's T11 it'slicence free in the UK which is a bonus.
