This fit my Philips Norelco S9731 perfectly
I did a lot of looking to try and find a comb for my shaver after it broke, including Ebay, etc.  They all cost between $10 and $20 it seemed, but had reviews all over the place.  I stumbled upon on this one somewhere in a way that made me feel confident about it (sorry, I don't recall where), but I was of course still skeptical because so many reviews seem fake these days.<br /><br />But it fits perfectly and appears very durable.  I've used it for months now, and cannot tell the difference between this one and the original.
