The one minor thing I did not like is that once the weight reading stabilizes, it "locks in." Others may find this a plus, but for weighing my pets it is a small nuisance. On my old analog scale I could step on the scale, read my weight, then have someone hand me the pet and read the combined weight (subtract mine to get the pet's weight). With this scale I have to step off the scale, wait for it to blink off, then get back on the scale holding the pet to get our combined weight. As I said, minor. I am not taking away any stars for this, just making a note of it. This was advertised as a highly accurate scale, and my test bears this out. I tested it using known weights (measured using an analytical balance) in the range of 20 to 140 lbs. Absolute error was never greater than 0.1 lb, and the extrapolated error at 180 lb (a typical male body weight) is -0.05 lb. This was estimated by applying a linear least squares fit to the data. The scale is very easy to use. I have not tried all the features, but after inserting the batteries I calibrated it, set up myself as "P1" (person one?) and had my weight, BMI, and maintenance daily calorie intake, in about a minute. For a routine weight measurement, just step on, it auto-activates, blinks a weight reading for a few seconds, and when that stabilizes (stops blinking) you have your weight. The back-lit display has large easy-to-read digits for your weight. If you have set it up for BMI and calories, they are a bit smaller, but still easy to read. My scale's location is well lit, so the back-light may not be necessary, but it also does not detract from the readability. This scale is stylish and attractive. I read one review (external to Amazon) which suggested that some people may be disconcerted by the glass top, as it allows you to see the floor underneath the balance. This is not an issue as far as I'm concerned, but FYI. The glass top is thick and sturdy.
