Product review (3 stars): IT'S FITS WELL IF NOT BENT
I rated the cap with 3 stars instead of 5 due to 1 of them being bent, causing the magnified area  not to lay flat on the stove. The seller forwarded boxed item, quickly. I don't know how the seller would have responded, but due to the small price paid, I didn't bother to contact them regarding the problem with the one cap. I would still recommend this seller to others.
