Works great for me!

I use it to transfer photos to and from my MacBook Pro, iMac, iPad 3, and iPhone 4 over the wireless network in our house without any problems. Using it for several months now. I find that the convenience it provides is worth the cost. The photos dont have to be in iPhoto or Aperture to send them over to my iPad or iPhone, and instead can just be on the Macs desktop. Very flexible app. I have never had a problem with it, and yet I use it often.
