I bought this to replace my mower babyliss I had for several years and whose guide is broken by falling. My disappointment comes mostly from the guide. Very flexible, the teeth do not stop to deviate and therefore there are cutting inequalities and therefore échelles.De addition, if you press a little too hard mowing, the guide Exchange notch (even without touch), so not great. If I had known I would have followed my first idea, namely buying a new shoe for my old mower, this is what I will do next week. By cons, self-lubrication is great and the cleaning system is nickel
