Query: Worthless

I have to say I regret this purchase even though it is so cheap. Cross grain dados are HORRIBLE. Tons of blow out. Straight grain dados are better but there are so many ridges on the bottom that it is a real time-waster to clean them up.I don't want to spend $200+ on a set but in the big picture they may save you a ton of time.
