PrivateWall review for InkGo POD Product Personalizer

I use this app for personalized products with the ability to upload pictures and get a live preview. Theoretically this is an awesome feature and even better that you can upload .psd for masking the products. Practically the app is not easy to understand, buggy and the support is no help or wont answer at all. Update: I cant publish any product through this app, it wont upload. Any changes you made are going to be deleted when the window is closed.
