dog remote training collar

Happy Friday! For today's SBIG (So Bad It's Good) post, I bring to you this weird Dogrtra Remote Training Collar. I have no idea what it does and actually am kind of scared to find out. (It looks like maybe some form of shock therapy, which... kinda scares me.) But I find it kind of amusing that the creators of it decided to make it much more stylish by providing a faux wood version of it, complete with matching remote control. If anyone knows any info on what this actually is used for, and/or how it works... please enlighten us!
