I am really impressed with these saucepans for a number of reasons.
Good big handles, great for arthritic/older hands.  Saucepans feel secure in my hands even when nearly full.
Good weight, not too heavy, but not so light that they are not steady on the hob.
Clear lids so you can see what’s happening in the pan without removing the lid. Small vent in lid to let out steam.
The pans give a good, even boil or simmer to the  contents, I have had pans which seem to boil the contents just around the side.

Just a small thing, but instructions are all on one small piece of paper and only in English, so no flogging through umpteen pages in 30 languages to find the bit you want.
