Its ok.

The iriffport is phenomenal. Very high quality, and easy to use. Line out and headphone jack are great. Ive had no problems keeping it plugged in, even with the lightning adapter.

The sound quality is exceptional. Support is fast and second to none.

The app is ok. Probably more three star, but the iriff is 10 stars. The app is extremely easy to use, adjusting settings is a snap. I just cant figure out how to get a decent sound? When I compare the amp and effects of this to others, it falls a bit short. Mainly the rock and metal distortion effects. They sound too fuzzy, to me and not enough clean heavy distortion if that makes sense.

Anyway thats my thoughts.
