I bought it when I got the Silhouette Cameo. It's not really necessary. I've been using my Cameo for 5 months now and haven't had to use a scraper yet. I'm sure it's a great product but if you're a new Silhouette user/buyer and just want to buy all the accessories just in case. My advice to you is that you don't really need a scraper. Instead, I would recommend simply purchasing additional mats and blades.
