Shred Neck?

I was visiting some guitar forums earlier this morning. Not sure if I was coping a little attitude from my illness or I’m experiencing a mild Turkey withdrawal or what, but I saw an ad for Shred Necks. I’ve never heard of such a thing, so I was obviously curious and wanted to investigate further.

Long story short, or short story long, it’s a tool to help guitarists warm up. It’s a miniature neck where you can practice scales or ‘strumming’ if you’re guitar is unavailable for some reason. I usually like guitar aides, but this just seemed weird to me. Am I missing something? Does this seem practical to everyone else? Do any of you use this tool?

I don’t know, for me, if I wanted to practice guitar, I would grab… my guitar. I play dry all the time. I work in my office and have it next to my desk at all times. If I get burnt out or frustrated.. it’s time for a rock break. I don’t get it, please enlighten me if I’m missing the point.

Here is a video I found which still makes it confusing to me.
