Don't strictly go by Demo day. I tried the Frantic on Demo day along with the Critical Theory, HiRoad and Nano Pearl. Loved the Hi-Road and Theory. Was not impressed with the Nano Pearl or Frantic. Wife loved the Shooting Star and we ended up buying her one. After we bought it, she couldn't get it to work like it did on Demo day. Polished, sanded, nothing helped. Could have been the conditions, the drill, who knows. My driller loves the Frantic and keeps trying to get me to buy one.
