It looked great at first glance. But after unboxing it, it didn't do what I expected. I'm 72 years old and had one like this years ago and when you squeezed it opened up and shrank when you were done. The ones I bought had to struggle to open and fold to close. I thought you should crack it, but after carrying it in my pocket I had to struggle to open and close it every time. So I am very disappointed and have stopped using it altogether.
