Review on 🔋 Revolutionary AIR SCALE: Battery-Free Digital Bathroom Weight Scale - Dynamic Body Scale with Large LCD Display, Wide Platform, and Measure Tape Included (White, 400 Pounds) by Veronica Wade

This electronic digital floor scale WITHOUT BATTERIES really works! In my testing, just one press (with my foot) of the charge button provided enough power for weighing. You then step on the scale and after a few seconds your weight will be displayed in pounds or kilograms - your choice. So why am I only giving it three stars? Because the scale does not provide consistent readings from one weighing to the next. I quickly weighed myself six times in a row, each weigh-in performed as follows: (1) press the charge button with my left foot; (2) wait until the reading reads 00.0 according to the manufacturer's instructions; (3) stand on the scale and wait for the reading to stabilize; (4) Get off the scale and record the reading; (5) wait (about one minute) for the display to clear; and (6) repeat. At my six weigh-ins I got the following results in pounds: 165.8, 166.6, 165.6, 165.6, 165.8 and 166.2. According to my testing, the scale reading can vary by a full pound from one weigh-in to the next. That may not seem like much considering that 1/165 is only 0.6%. However, people who carefully monitor their weight really want to know that their weight measurements are reliable up to, say, 0.2 pounds. My old-fashioned mechanical floor scale from the 1970's shows such reliable repeatability; These newfangled battery-free scales aren't that much. This product also includes a tape measure. I assume this is for measuring your waist as it is only 60 inches (5 feet) long, too short to measure most people's height.
