I could't agree more with previous reviewers with respect to poor cutting perfomance with this razor. I purchased this razor, model F4790, 6 months ago when my old Remington, model MS2-370, started to die. I had the old model for many years, so I was not surprised. You would think that over the years, a product would improve. My old Remington, model MS2-370, performed much better. The very first Remington Microscreen razors were the best. They keep going down hill. Why? I don't know. Fortunately I was able to order my old model Remington, MS2-370, which apparently is no longer made, over the internet. They are still available at a reasonable prices if you search around.
I suspect that the people who engineered the new models don't use them. I wish that they would take one home and live with it for a while. Even using a good pre-shave lotion and well lubed screens cutting performace is lousy at best. My advise is to look for and purchase one of the "old" MS models. They are much better.
