I did a lot of research on this blade and read mixed reviews on buy it works great to dont buy it. I have only used my Cricut a couple of times because I have a busy schedule so I am still learning how to use it. I have to say when I make all the adjustments to cut card stock it seems at random times not to cut right on one letter. I also read you can cut felt with this blade not so true. You have to keep in mind your machine will only cut items that sit securely to the mat (just use common sense). I tried the felt that is stiff and it made the cut out but not very clean cut (yes I had the right adjustments). Also if you read your manual it has a suggestion not to use your Cricut all the time with thick items because it is not good for the machine, it will wear it down fast. The price you pay for the deep cut blade on Overstock is fantastic. I am a firm believer sometimes you will just have to buy the product and try it for yourself.
