Product review (3 stars): Just OK.
These rings are OK.  They do fit my stove and replace the old rusted discolored rings but are not of very high quality. Where my old rings had a high smooth chrome finish, these are have a slightly pebbly finish as if the manufacturer could not be bothered to polish the metal before the chrome process.  I expect these to last about three years and then will start to rust and will need to be replaced.
