Review on POWERTEC 13 Inch HSS Replacement Planer Blades for Ridgid Planer R4330, R4331, TP1300LS and AC20502 - Set of 3 Knives by Mike Bigglesworth

UPDATE: Got more blades and they were right. Only aggravated by the inconvenience and disappointed with the company's response to ZERO. Upgraded to 3 stars because the blades are ok only people selling them. I've bought these blades four times now. The first 3 passed with no problems. This time someone didn't pay attention to the labels and I got the wrong product. As a carpenter, I need these blades for my job! Pay attention! I'll see how the customer support works [and how accurate it is] and update my review.
