I purchased this item new and used it twice for height measurement. The transparent seal on the display has not been removed. The range is 0 to 2.4 meters, and you can easily measure the length of objects and the width of rooms. It's sure to be useful in various situations, such as moving or arranging furniture. 【Convenient to Carry】The compact and lightweight design makes it easy to carry and store. It's convenient for use at home, as well as when traveling or going out, and supports a more comfortable daily life. - Brand: Umimile - Model: Infrared Height Meter - Measurement Range: 2.4m - Display: LED Display Umimile Height Meter Digital Infrared Measurement One-Handed No Wall Mounting Object Measurement Measures up to 2.4m Easy to Use Growth Record Quick Cute (Blue)
