In my kitchen we go through spatulas and scrapers at a rate of about one every 2 years. Over time the rubber or nylon eventually wears out and it tears after which they really are no longer good for use in the kitchen (though the handles can be reused for other purposes). This is a nice set of silicone scrapers and so far I am very happy with them. I suspect they will last quite a while longer than the others I have used.
