Review (5/5): My daughter bought me this as a Christmas present in 2007
This is the best raiser that I have ever owned. I change out the blades about every year, but it has kept working well and I leave it plugged in all the time. Never had an issue with overcharging and it cuts nice and close. Some areas have to be gone over a few times, but even with a blade you sometimes miss a few hairs. I don't know how well Norelco's replacement is, but if it uses the same technology, it should be an excellent product.
