Review on Yakamoz Tongue and Groove Matched 4-Inch Pieces by John Hall

After receiving the router bits and holding the first one, I was concerned as soon as I turned on the router that it would vibrate so badly that my router table would go over the counter and cause sparks due to the spindle lock on my router . . I removed the router and took it apart to find the hole is in the middle? the cutter was not round or centered. not what i expected and not safe to use. I am not satisfied with this purchase and will be sent back to the seller. UPDATED REVIEW - This company's customer service is excellent. They sent me a new set of cutters, they work great. Many Thanks,
