I wanted to get into woodworking so I got everything I needed, this set was part of that and the bits did not disappoint. Each comes with super sharp blades. I've made over 20 doors for my kitchen and several drawers with a 1/4 straight cutter for most cuts and the blades are as sharp as the day I opened the drawer. The suitcase is good too. Photos and measurements are printed on the inside so you know what goes where and which bit makes which fine cut. Finally a very strong shaft that I don't see breaking. Used bits on a Porter Cable router/router table and there was no vibration at all allowing for precise cuts. Look, you get a lot of attachments at a really good price compared to what's available on the market. I will definitely use this brand again if I need more beats in the future.
