Review on InstaTrack Digital Bathroom Scale Display by Crystal Barter

To be honest I bought this scale for the looks. As the pictures show, it goes very well with glass tub doors, glass shelves (on which to store it conveniently), marble tile, and mostly brushed nickel fixtures. Accuracy is not that important in my opinion. But you *wonder* how accurate that is? Am I really supposed to believe the pound percentages shown, or are they just meaningless? First, these scales need a solid surface to stand on; it does not work properly (value too low) on a bath rug or deep pile rug. In particular, the floor must only press on the feet and not on other areas of the underside of the scale. But the ground doesn't have to be very flat. There are no marble tiles in my bathroom. However, I only get the maximum random deviation of 0.2 pounds when moving the scale. I can't create a more random variation than this one. (The reported random variation of 1.5lbs leads me to believe there is a problem with these weights. It seems natural that your total weight is found by adding four feet's weights together. So if even one foot is inaccurate (This can be done. Readings are very random depending on how much of your weight is on the affected leg.) As for accuracy, the manufacturer claims it is "very accurate" (meaningless) and "to within 0.2 pounds accurate” (this is the accuracy of the measurement or how accurate is reading a less accurate measurement?). Like others, I decided to take a test based on my weight of 128 pounds measured at my doctor's office. As soon as I got home I measured my weight on my own scale, ** didn't eat or drink between measurements, didn't go to the bathroom between measurements, but in the same things, in the same things. my pockets**. I got measurements of 129.0 and 128.8 (remember the random 0.2lb variation on my rough marble tile floor). Does the fact that 128.9 isn't 128 mean my scale is less accurate than 0.2 pounds, despite the manufacturer's apparent assumption? Not necessarily. The scale in my doctor's office read 128 with no decimal places; Therefore, the actual weight measured at the doctor's office could be anywhere from 127.5 to 128.5 pounds. Medical scales have a measurement error of 0.5 to 1 pound, which seems reasonable. So my data doesn't contradict the apparent assumption of InstaTrack's 0.2lb accuracy. Another reviewer wrote that the known weights of 10 and 20 pounds were accurately measured. Since I don't have calibrated weights, I used four liter containers of water. Using a new kitchen scale with a range of up to 11 pounds, I measured containers weighing between 8.59 and 8.63 pounds for a total of 34.44 pounds (I calculated 8.35 pounds per gallon of distilled water, which is 0. equals 14 pounds). A container would yield 8.5 pounds instead of 8.6, but containers don't necessarily hold exactly one gallon. If so, I don't know how to explain that 8.63 was distilled water and the rest was spring water. Obviously they are filled by weight and not by volume. And the kitchen scale claimed to be a "high precision strain gauge system". Well, at least they and the older "Good Cook" 1-pound mechanical kitchen scale, which is dead accurate when my measuring cup came out exactly the same 11.5 ounces for a coffee cup, gave it.) When the water tanks were put on InstaTrack, they measured 34.4 pounds, the right amount. Since a kitchen scale and an InstaTrack scale would hardly match exactly if one or both were inaccurate, and the same goes for my old kitchen scale and measuring cup, the alleged accuracy of my InstaTrack appears to be correct. Update 05/27/21: I seem to recall that the scale at my doctor's office read 128 pounds. But actually they showed 129 pounds; it's right here in the "followmyhealth" section. The doctor's scales and InstaTrack actually measured the same weight. Sorry for the confusion.
