I ordered the self opening scissors for my sister who was finding it difficult to hold scissors due to loss of muscle strength - she has leukemia and kidney problems. She finds these much easier to hold and manoeuvre than conventional scissors, and is very pleased with them. I was worried that she would find the clasp which holds the blades together difficult, but she has no problem with opening and closing it. She is very pleased with them, and would rate them as 5 out of 5.
