BEATS A HOT WATER BOTTLE: With consistent and controllable warmth and no need for boiling water, the HK44 is the fuss-free way to beat the chill. ADJUSTABLE TEMPERATURE: With 3 electronically regulated temperature settings, your heat pad is always at a temperture that suits you. NOTE: It will take approx. 30 – 45 mins for the device to reach the maximum temperature. OVERHEAT PROTECTION: The heat pad will automatically switch off after 90 minutes use and is supported by the patented Beurer Safety System. Output in watts: 100. PREMIUM FIBRES: The super-soft, micro-fleece fibres are cosy yet breathable and Oeko-tex 100 certified to be kind to skin. MACHINE WASHABLE: Simply detach the power cord and temperature control and pop in your washing machine at 30°C. Note: Once used allow the pad to cool down and then when ready, use again. Also store the product flat with nothing on top of it. Note-The heat also dissipates into the room if the product is switched on but isn’t properly being used. So if you are just touching the product with your hands, rather than using the heated product as you should, due to the heat dissipating the product will feel cooler than if you were using the device correctly by sitting using the device. Then the heat will also feel different when the product is in use and the heat accumulates with the device being used on-top of / over the user correctly.
