I'd say it really depends on how often you use it, and what you blend in it, but I'd say 20-30 years for any small home appliance that you use daily is pretty amazing. The Ninja I got a few years ago is already falling apart (mainly the pitcher cover) and it is a total pain to clean. Doesn't do a great job of blending some stuff either, but it was a solid intro blender. Looking forward to my Vitamix though!Is 20 years a long time for a blender? I know my mother used the same blender for at least 25 or 30 years. I don't know what she paid for it, but it was probably from Sears.
