Query: Not so Great

Had it a year, it worked ok. But now, a screw has worked loose from the top part, and it prevents the head from tilting back. Total dis-assembly is required to fix this.There is no excuse for a screw working loose! Bolt it, rivet it, pin it, or Loctite it! I'm handy, so I'll fix it, but anyone else would have to trash it.The motor is beginning to smell as well. Can't recomend this machine, it dosen't last.
