【Never Buy Batteries Again – Self-Powered Technology】Unlike traditional battery doorbells that require regular battery changes or recharging, this Gobikey wireless doorbell uses a self-powered transmitter. Each press generates its own electrical power, eliminating the need for any batteries in the push button. No battery to replace, no hidden costs, and no sudden failure – true maintenance-free operation for years to come. 【2 Receivers Included – Cover Your Entire Home】Most wireless doorbells come with only one receiver, but this Gobikey cordless doorbell includes two plug-in receivers. Place one upstairs and one downstairs, or use them for front and back doors simultaneously. Never miss a visitor whether you’re in the kitchen, bedroom, or garden. No need to buy an extra receiver separately. 【1000Ft / 300M Stable Wireless Range】Enjoy a reliable signal with up to 1000ft / 300m range in open areas. Whether your door is at the front of a long driveway, on a detached garage, or around the corner, this doorbell wireless kit maintains a stable connection across varied home layouts. Strong enough for most UK homes and gardens. 【IP55 Waterproof & All-Weather Durability】Rated IP55 waterproof, this Gobikey door bell withstands rain, snow, and dust without issue. Designed to operate reliably in temperatures from -20°C to 60°C, it holds up through British seasons – from winter frost to summer heat. Built to last where other doorbells may fail. 【52 Chimes, 115dB Volume & 7-Color Visual Alert】 Choose from 52 built-in chimes with 5 adjustable volume levels up to 115dB – louder than most standard doorbells. The receiver features 7-color flashing LED lights, and can be set to LED-only mode for silent visual alerts. Perfect for noisy households, hard-of-hearing family members, or when a sleeping baby needs quiet. 【Easy Installation & Memory Function】Install this plug in doorbell wireless kit in minutes – no wiring required. Simply mount the transmitter with screws or adhesive tape and plug in the receivers. The built-in memory function saves your chime and volume settings even during power outages, so you never need to reconfigure after a cut., Manufacturer: Gobikey
