As the product description states: can choose "save to" format, quality level of saved image, save location, startup at login, and much more.

Simple, straightforward, very nicely done, IMHO. The Apple keyboard command save-image function is pretty simple, but now saves to PNG only. I had used SnapNDrag a lot also; a nice alternative, but this is even simpler and nicer to use than SnapNDrag, again IMHO.

I like being able to do everything from drop-down menu from menubar.
