I had mowers ... but often the shoe was not accurate, or worse, suddenly passed to minimum and presto, a hole (like my Philips! This takes surprisingly well, I tested Pressing the hoof but no, I really have activates the handy button to change the size. Besides there really has an impressive selection of cup sizes allowing just making the same haircuts storing the positions. I hesitated between this model and other highly rated, Remington HC5810, but I could not find convenient to have to change for each cut shoe size (unless you want a military cut which is not my case) . With this Braun, I'm really happy! And thank you to Amazon for speed: controlled the afternoon, received the next day at noon in Premium!
