I have a Ridgid 4331 13” planer. I have had for 4 or 5 years and use it sparingly but it does get used. I think I’m on the third set of blades. I had it replaced free of charge by Ridgid when the machine started sounding like a coffee grinder about 6 months after purchase. Don’t know what went wrong. Took a few phone calls and several weeks but they honored their warranty. Can’t complain about anything with this planer.
