Summary: I bought a Remington 4790 electric razor several years ago. Last week one of the screens broke through, so I searched around and found the one that was the right replacement screens, (but also had new shaving heads) with the best price at Walmart .
Summary: This Product is made of cheap material compared to the original one that the shaver came with. The cutter rollers will come lose and are thinner thn original ones. foil feels very rough on skin. it irritated my skin right away. Remington is not making these shavers as they used to.
Summary: SP290 Remington replacement head has worked very well for me. In two years I have replaced the head only once. I just bought a second head, which is not yet put in use. Have been very satisfied with the Remington razor using the SP290 head.
Summary: I bought two of these replacement foils less than a month ago and I am already on the second one. Problem: On the third use the foil frayed and shredded my face. I always shave with a razor, but I got the electric shaver for the days that I don't have a lot of time.
