Carbide broken on one tooth right out of the box - pieces in the shrink wrap plastic so I never even removed the blade from the plastic. OEM packaging and shipping container in perfect shape so I suspect it was shipped to me this way. Called Freud first since it appeared to be defective and not damaged in shipping. Freud told me to send it back to Amazon. Amazon is having UPS pick it up and will refund but not exchange since apparently it did not come directly from them. So I must now wait for the return shipping, wait 2 days for refund, re-order, and wait for it to arrive - again. I will update this rating once I receive a working blade.....Chris
