Braun Series 3 Men's Electric Shaver (Model 300s), a shaver designed for dry shaving and smoothing men's beards. Key Features and Specifications: * **3-Flex Cutting System:** Flexible foils automatically adapt to facial contours and details for a close and precise shave. * **Quick Charge:** A 5-minute charge is sufficient for one full shave. * **2-way use:** Allows cordless shaving using the battery or direct use while plugged in. * **Waterproof:** The shaver is fully waterproof with an IPX7 rating, making it easy to clean the shaver head under running water. Correct Usage for the Best Shave: * **Ideal Timing:** It is always recommended to shave before washing your face or showering, as the skin and pores are less swollen. * **Correct Angle:** Hold the shaver head against your skin at a right angle (90 degrees). * **Shaving Technique:** Gently stretch your skin with your other hand and slowly move the shaver against the direction of beard growth. Care and Cleaning Instructions: * **Quick Cleaning:** Turn on the shaver (without the power cord) and rinse its head under warm running tap water until hair residue is removed. * **Brush Cleaning:** Unplug the shaver, detach the foil and cutter block, and gently press it on a flat surface to remove hair. Use the brush to clean the inside of the shaver head (avoid brushing the foil and cutter block itself to prevent damage). * **Head Replacement:** To maintain the same shaving efficiency, Braun recommends replacing the shaver head approximately every 18 months.
