they have rivet on it this mean it will last Long enough. I have bought one blade from Amazon it lasted only about 2 years…. But do you remember how long you had your blade the first time…? This one will last as long as the original one because it is exactly the same if you buy 3 you save 25$ wich is the delivery charges so I recommend 3.. I believe my cuisinart motor and pieces are solid enough….:-) be carefull on eBay parts come from us. and cost a LOT more
