I use this to shave my head about twice a week and these replacement blades are perfect for me - inexpensive, easy to change out and sharp! Unless the rotary engine dies (or they stop making them), I don't need anything else. In addition, with proper care, this is a great solution for extending the life of the trimmer and generally a great value for ease of use. . As for the price, as always, make sure you're getting an official Wahl product. After reading the reviews here I seemed to have taken a chance and gotten lucky. However, I can only recommend it, just not at this price. Almost half can be found, sometimes even less. Ask your local barber/salon to make this easier.
