wrote the seller and they confirmed - cannot replace blades!
although this works great - i cannot recommend simply due to the fact that you cannot replace the blades.  after 6 months - i kept feeling a tug even if i rinsed the device AND put oil.  I tried to replace the blades with the sweet LF blades - like someone had mentioned in the reviews.  did not work - the plastic covers would not snap back in.
