1. Easy Installation - Tired of reading various paper manuals or watching instruction videos to get the clock working? We've succeeded! This mini shower clock has only one time setting button, which can do it all! All you need to do is simply turn the button left or right to get the correct time period and insert the AAA battery (not included). 2. Small Size, High Performance - This clock is only 7.4 cm in diameter and 3.8 cm in width, but a small size can also have a large display! All numbers and minute scales on the dial are enlarged for quick identification. Acrylic, known for its extra transparency, is the clock's surface. In addition, the clock case is made of high-quality silica gel, the best guarantee that no water droplets leak into the clock. 3. Suction or Stand - This is not only a good choice in water-rich places like bathrooms or kitchens. If you are looking for a quiet and simple clock for your desk or bedroom, this clock is also a good choice. It can be firmly sucked onto any smooth surface, just press the suction cup behind it, or the solid silicone case is enough to support the clock. 4. Installation Measures - Use a damp cloth to clean the suction cups and target surfaces and make sure there is no dirt on them. If the clock needs to stick in the same place for a period of time, it must press the suction cup every day. If you feel it is too tired to stay in hot water, you can also put the suction cup in warm water for 10-15 minutes at any time to refresh it.
