Hundreds of thousands (actually I think it may be over a million with the first iRig figures included) seem to think very highly of the #1 portable/mobile guitar interface.
Seriously, though, we wouldn't keep making it if guitarists weren't using it. We've even seen great guitarists like Alex Skolnick using it to warm up backstage and at home, or Slash who really did write MANY songs for his solo album using iRig & AmpliTube in hotel rooms and the tour bus. iRig has become part of the vernacular for guitarists these days, and we're quite flattered, humbled, but also proud of this.
