Shipping was incredibly fast for this item so no problems. However, the first time I use a 3" router bit, I turn on the router and the router bit flexes in the shank and hits the plastic guard on the underside of the router bit. Then he chews on the guard and sends a shrapnel in my face. It was a good thing I wore goggles because bits of plastic hit my chin and bled. This photo was taken right after cleaning my chin. DO NOT PURCHASE THIS PRODUCT FOR SAFETY REASONS.
