Perfection not so much

Updating my review Oct 06 2016
Hmm hadnt used it in a few months. Now it cant pair with second device. Searches for a second iOS device and freezes. I suspect the app is no longer being supported so..caveat emptor

I was using another app for synching two devices for L and R, it quit working in ios7.
I found Stereo and it works on wifi or Bluetooth. Great interface. Painless to set up.
You wont be disappointed. Best buck Ive spent in awhile!
