I use them & I like them. I have had no skipping & I just changed to my second one this week. I have cut out alot of fabric. I gave 2 packs to my quilting girl friend & she is still using the 1st blade, no problems. Loves them.
Really don't know why they would cut any different then the olfa ones, they seem to be the same blade.
I would suggest that you at least try one package of them & determine if you like them. Some times people use them differently, not holding them straight etc.
