The Remington R-4130 is a cordless, rotary electric shaver that features a Flex360 with titanium flex and pivot technology. Unlike its predecessor, the R-3130, the R-4130 can be used either with a cord or without a cord after at least 16 hours of charging. Once fully charged, the R-4130 can be used cordlessly for approximately 30 minutes before it requires additional charging. In addition, the R-4130 features a charging indicator that displays a green light as the unit charges. The R-4130 also boasts three dual track rotary heads with durable titanium coated blades that utilize Flex360 technology to pivot towards the face in multiple directions, thereby offering a closer, more comfortable shave every single time, not to mention neck pivots, World Wide voltage, and a pop-up trimmer. The Remington R-4130 is priced at $39.99. If purchased from the manufacturer, the R-4130 comes with a power-cord, a cleaning brush, and a 2 year warranty. Replacement screens/cutters (SP-3141) are available from the manufacturer.
