This did not fit the Norelco AT 830 as stated
The fit was close but it did not fit.  It was tight when snapped into place and when you tried to close it the silver perimeter would not close because the side tabs were to long.  After comparing it to the original my husband decided to cut off the two side tabs.  It now fits and closes.  One only knows how long it will work.
