I've been using it for 6 years now. Haven't had no problem except for some buttons not functioning properly, which was remedied by a little cleaning with WD-40.Amp modelling is satisfactory, effects emulation is cool, though trying to compare them with their hardware counterparts would be foolishness.It's great to learn about various amps, effect units and stompboxes, their parameters, learning how to dial a tone to your liking.Interface is quite detailed and simple.Additionally, it can be used as a USB interface to directly record you guitar to your favorite DAW.Overall, a great choice for beginners and intermediate players alike.
