DISCOVERYOPT ED-ELR 5-40X56SFIR FFP: How does it compare to other budget optics?

A scope packed with a ton of features that seems to be well built. Falling a little short in one area but definitely has the ability to get the job done depending on its intended use... Do you think this might be something you'd pickup?
