Philips Norelco Shaver 5100 (Model # AT928/41) has TripleTrack heads that are designed to cover 50% more in every stroke for a faster and closer shave. Aquatec Technology allows you to shave wet with gel or foam (in or out of the shower) for extra skin protection or dry for convenience. The Pivot, Flex & Float System allows for better contouring around the neck and jawline. By independently pivoting, flexing and floating, the heads adjust to the face's every contour to quickly catch every hair. The Skin Protection System has rounded low-friction heads that adjust to the contours of your face to limit skin irritation. The integrated pop-up trimmer conveniently trims sideburns and moustaches. The Lithium-ion battery delivers 60 minutes of cordless shaving after a 1 hour charge. A 3 minute quick-charge provides enough power for one cordless shave. Simply rinse device under faucet for easy cleaning. Shaver 5100 comes with a charging stand. For best results, replace shaving heads with HQ9 replacement heads every 12 months. Packaging includes: Electric shaver, protection cap, power cord, cleaning brush, plus a bonus charging stand and travel pouch.
