A very good program, I've been using it for 3-4 years now. It's faster than the classic Snipping Tool in Windows, which comes by default.

A program that I have been using for 1-2 years which has made the job of screenshotting a lot easier. The easy, yet complex customization makes it a go-to program and easily tops Lightshot or Snipping Tool.
