I myself haven't had any bad experiences, but I'm a newbie. I am very serious about safety. I use all my guards, splitters, safety glasses, ear protection, dust mask, push sticks, etc. I generally double check myself before turning the machine on.
The only time things get a little hairy is when I've been cutting sheet goods by myself. I plan to get a guided system in the near future (EZ or Ftool) to rectify this problem.
I did have my first ejection on my TS (not a kickback), but I was standing to the side so it was nowhere near me.
