1. Easy Installation - Tired of reading various paper manuals or watching instructional videos to get the clock working? We've succeeded! This mini shower clock has only one time setting button that can do it all! All you need to do is turn the button left or right to set the correct time period and insert the AAA battery (not included). 2. Small Size, High Performance - This clock is only 2.9 inches in diameter and 1.5 inches 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 casing is made of high-quality silica gel, which is the best guarantee that no water droplets will leak into the clock. 3. Suction or Stand - This is not only a great choice in humid environments like bathrooms or kitchens. If you are looking for a quiet and simple clock for your desk or bedroom, this clock is also a great choice. It can be firmly attached to any smooth surface, just press the suction cup on the back, or the solid silicone casing is enough to keep the clock in place. 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 stay in the same place for a long time, the suction cup must be pressed firmly every day. Additionally, if you feel it's too tired to stay in hot water, you can put the suction cup in hot water for 10-15 minutes at any time to refresh it.
