This scale boasts an oversized platform made of impact resistant tempered glass. There is no need to tap it before stepping on or waiting for it to calibrate, since it is auto-calibrated. I like that it automatically turns off after displaying your weight to save the battery (which it runs on one lithium CR2032 battery-which is included). There are four precision sensors that weigh up to 400 pounds in 0.2 lb increments. You also have the option of displaying your weight in pounds or kilograms. I like the ease and simplicity of this scale and put it in my upstairs bathroom for my kids to use. I have owned several different Ozeri products, and I am pleased with all of them because they are quality made and never disappoint. I definitely recommend this scale, especially since it consistently displays accurate weight, and you will not be disappointed! I received this product at no cost and my opinon expressed is a direct reflection of my experience with this product.
