Totally worth it!

The app is totally worth buying it. I use it with Lenovo Thinkpad T420 and Win7. Here, during studies this is my only way to view and edit photos with colorful Retina. :)
Ipad mini 2 works just like additional monitor, with full range of resolutions.
Great thanks for the author, incredible work.
