I took it out of the box for photography. This digital height meter is easy for anyone to use; just press a button and you can measure your height immediately. Simply attach the bottom of the giraffe to a vertical wall to create a height reference, then press the button. Measurement is complete in just 3 seconds with a "beep, beep" sound. Your height will be displayed on the LCD screen on the neck. 【Mechanism】 Two speaker sensors in the neck send out sound and receive the echo from the floor. The time it takes is measured and converted into height. 【Recommended Points】 Haven't you struggled with conventional height meters, which were very large or required installation on a wall to measure height? With Shinchou Wakaru, anyone can measure their height instantly. The product is small, doesn't take up much space, and is easy to store. ■ Batteries: 3 AAA batteries (sold separately) ■ Material: ABS ■ Body size: W80 x D52.5 x H229mm ■ Package size: W85 x D53 x H235mm ■ Manufacturer: Hashy Top-in.
