This is a fairly decent block plane for the price.  If you're just doing rough carpentry work it will be fine out of the box (after sharpening the blade).  If you want to use it to make furniture you'll have to flatten the sole of the plane and make sure the blade sits flat on the bed.  If it doesn't you'll need to file down the high spots.  Don't expect it to perform like a Lie Nielsen or Veritas plan because it won't.  There's a good reason those planes cost as much as they do.
