Bought it for BST-1 bass shakers, (simracing/music) but it was too weak for them, so I use it for smaller (15W) exciters now (Sim pedals), there its okay.
Had a faulty one that went up in smoke, got it replaced.
Knob is a little noisy when used, but other than that its okay, for the price for low wattage stuff, with integrated USB DAC its good value.
