Yeah, should have mentioned that. But with the ease of shave it provides I'm happy to pay for the replaceable blades. Cheaper than buying high end shaving products as they are released just to be let down time and time again, and even premium product's blades go full after a few years and are. Or usually user replaceable. I know it's subjective but this is by far the best shaving experience I've had, I almost look forward to this mundane task. Hopefully the blades DO last 4 months but only time will tell.
