For a free watermarking application, it is good enough for me. I have plenty of time on my hands to sit down and individually watermark each photo that I want to. The free version only lets the user to watermark five photos at the most, and even then it tends to get a bit sketchy. They won’t let users change between photos on the screen and edit the watermarks individually. Lastly, the quality of the text in the program is not the best and should be double checked after export.
This is fine for me since I have a lot of time on my hands and it is only one of very few programs that is free So if you want a really nice application that allows you to more photos at once and not have to worry about sketchy work, this is not the program for you.
