Shocking reason #1. The Jolt electric chair prop just looks creepy. Lots of attention to detail.
Shocking reason #2. Flip a switch and you will hear and electrical wind up followed by an intense thrashing by the victim. In fact, the thrashing is so violent that you will have to chain or bolt the chair down.
Shocking reason #3. The price. $1795 plus $595 for shipping. Damn.
