Thanks for the comment. Sorry for the translation tool, as I am not good at English. My personal opinion is that it is worth it. The fact that you can press the buttons with a fitted fingertip, so you can press them with fewer mistakes, and the fact that you don't have to move each button, so you don't have to search for the location of each button is great. I just have the impression that the price is a little high. Translated with www.DeepL.com/Translator (free version)
