To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought it twice. First time I was fully satisfied with my purchase but this time I can't believe it's from the same company. They changed the material. This time they're cheap, useless tools. They don't close properly and the tips are anything but sharp. The surface is not smooth at all, almost like a nail file so it's impossible to clean it well. If someone from the company reads it PLEASE DO SOMETHING ABOUT IT IT'S HORRIBLE!
