Set Contains: 1 X HF3531/01 Review: Good product but how useful? - The product works very well however, no issues at all. Nice design and cool features. However I haven’t used it much since it takes a long time to switch on and off (which defeats the purpose of it if you don’t). I regret buying it personally as it costs quite a lot but I recommend it if you need a circadian alarm clock. Review: Glad I never listened to the 'never happy' bunch. It's a good clock. Keeps excellent time and does what it is made to do. Why some go on about the sound of the alarm and others that can't sleep because the clock face is too bright well it's a mystery to me. ## Features - Clinically proven to work with radio function and 7 natural sounds - 92% of users find it easier to get up in the morning - The Wake-up Light eases you into the day by re-creating a natural sunrise - Dimming light and sound gently send you off to sleep - USB port for mobile phone charging ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B074W91YPG | | Batteries required | No | | Best Sellers Rank | #63,972 in Health ( See Top 100 in Health ) #14 in Wake Up Lights | | Customer Reviews | 4.2 4.2 out of 5 stars (859) | | Date First Available | 24 November 2017 | | Finish types | Painted | | Included components | Power Cable, Cord | | Item Weight | 730 Grams | | Item model number | HF3531/01 | | Item volume | 1 Liters | | Number of pieces | 1 | | Product Dimensions | 7.83 x 5.75 x 7.56 cm; 730 g | | Specific uses | Inside | | Warranty description | 2. | ## Product Details - **Base material:** Plastic - **Finish type:** Painted - **Item weight:** 730 Grams - **Lamp type:** LED lamp - **Product dimensions:** 5.7D x 7.8W x 7.6H centimeters ## Images ![SmartSleep Wake-up Light, Coloured Sunrise and Sunset Simulation, 7 Natural Sounds, FM Radio & Reading Lamp, Tap Snooze (Model HF3531/01) - Image 1](https://m.media-amazon.com/images/I/51A5fC-Q-jL.jpg) ## Customer Reviews ### ⭐⭐⭐ Good product but how useful? *by M***A on 21 January 2024* The product works very well however, no issues at all.
