With Actifry 1.5 kg purchased in January 2012, the first blade was successful until June 2014 (+ 2 years) with a use of several times a week for many amateur home fries ... The second blade, found on this site and delivered 48H chrono (thank you Amazon), performed his services from mid-June 2014 to March 2015 (9 months) with the same use. This is the ratchet system, which keeps the blade and allows it to rotate, which in 2 cases dropped us ... The engine is perfectly door meanwhile, the better. So super convenient to find a replacement blade easily ...
