The quality of this product is so obviously poor that I have not even used it. I'll send it back immediately. There is a hole in the box which is disappointing but not a deal breaker. Then I opened the box and found that there was some kind of sticky residue on all the parts. I don't know what it is but it looks like a mixture of rust and cheap oil. That makes me think these aren't new beats, maybe refurbished ones. Also, the paint on the bits will peel off if you just take them out and put them back in the box. Of course, quality doesn't matter here. Save money and buy more. reliable brand or something for your router bits. I will never buy from this company again.
