I have had this chopper for years now and have never had any problems with it. I use it about three to four times a week. I haven't had to replace the blades yet. It comes with four parts and features (cover, blade, bowl, and base). It is so easy to use. Lock the bowl onto the base, put blade in bowl, then add food (don't over fill - there is a line not to put food over that line), put the lid on. That's it, simple as 1, 2, 3. It is just as easy to clean it as it is to use it. You can wash the cover, bowl, and blade in hot, soapy water, rinse and dry or put in the dishwasher. Don't but the base in the dishwasher or put into water. To clean the base, you just wipe with a damp cloth, then dry. It is powerful, only takes seconds to chop. Infact, if keep on too long it will over chop and you'll have mush. I'd say that it is very durable. I have dropped mine quite a few times and didn't crack or shatter. I like this chopper so much, I bought for my in-laws and son. Make great gifts.
