Somehow I've gotten on the Groupon mailing list, and I can't seem to get off... I opened the latest email to (once again) unsubscribe, and saw this piece of gimmick: It's called the "Chord Buddy" and claims to be a "guitar learning system". By pressing one button, it allows you to play either a C, G, D or E major chord. How the fucks is this a guitar learning system?! It doesn't teach you to play guitar... It just enables you to play four major chords without actually knowing the chords! It looks more like 'Guitar Hero' for the real world. Apparently, this product is brought to us by that reality game show called 'Shark Tank'. I'd dope-slap the parent who bought this for their kid.
