This is not good. Very bad. I made it five years ago. One side is crooked and the other side is flat. The blade is uneven. I didn't measure it in advance and didn't draw a line. After the anesthetic, I opened my eyes and closed them many times. He opened my eyes there. Now it's like two swollen eyes hanging on my eyelids. I haven't dared to find a place to repair it for five years. I'm afraid I will find a better one.
