I love that this tool is easy to use for even beginners! The interface lets me know what options are available as well so there's no confusion about how much power should be used (or not).
There isn't really anything bad i dislike with wimsmob retoucher; however if your looking at an affordable option then keep searching because other tools do have better quality control features than WM does but they're more expensive too - which means we lose out here ;-) But overall its super great value compared to all of my previous attempts when trying different editing apps such Photoshop Express/PicMonkey / PixlrExpress ect..
