I'm a big fan of these bits. I own a custom shop and am tired of spending Lara's money on designer tailors. After trying this brand I was very impressed, they work great and there is a very wide range of profiles. You have become my prey. I mainly work with MDF and softwood and haven't noticed any noticeable difference to the high-priced cutters. For the money, even working with hardwood I would buy them, I just can't speak to durability when they only work with hardwood.
