Easy to use, no need for any additional software or plug-ins as it is integrated with Photoshop CS6 (or higher). The application can be slow sometimes while editing large images/files but that's just one of those things you have deal with when using this type of tool in general - not something specific about picTER itself! I am solving problems related to image retouching during my workday so speed matters most here. It allows me to quickly edit multiple photos at once without having to open each file separately which saves time AND helps keep track if there are changes made between edits since they will show up right away after saving instead of waiting until next day like before.
