Recommended to monitor changes in your health. Great choice

Same model scales used in most Drs. OfficesYou can rely on their accuracy

Scale was easy to assemble and it looks good in my gym.

8/11/23 UPDATE! We have used this scale for nearby 2 years now and absolutely love it! It is accurate and dependable.A couple of hours ago this scale would have received only 1 star. I received the package (well packed) right before noon. I opened it and tried to assemble it. Folks, this job should be a no-brainer because all you have to do is insert the column into the base with 4 nuts and hook the steel rod at the base of the scale, stand it up and weigh yourself. I had already read the instructions online before receiving the product and read the reviews and questions posted on the website so I decided it would be an easy task.Admittedly I am not a handy person but with this scale one should not have to be handy. However, after working with it on and off all afternoon, I gave up. That hook would not stay on the rod when I stood it up.When my husband came home that evening, I asked him to look at it. He is good at "seeing" things and being able to figure stuff out. Just a few minutes into working with it he realized that there was no tension at the base rod therefore something had to be unhooked, broken, or left out at the top of the scale. Sure enough, the steel rod was unhooked in the top part of the scale (which is supposed to come fully assembled, not needing any fiddling with). He hooked it, then went back to the base and this time there was tension there and he hooked the bottom hook to the steel rod and we were able to weigh.So if you're having difficulty hooking the bottom of the rod (especially if there's too much play in it), look at the top part to see if it's unhooked there.I will try to post an update to this one after I use the scale some. When we weighed ourselves, the weight appears to be accurate right now.

This scale gives me the accuracy and precision I was looking for that I didn't have in cheap electronic bathroom scales. I showedthat its mass measurements are accurate by calibrating it with water of a known volume, using the density of water at room temperature to calculate the exact mass the scale needed to give me, and got the right answer to within the measurement error of the scale and the volume measurement instrument. I measured its precision to be plus or minus a half an ounce or so, depending on how you choose to quantify this variable.For two standard deviations as the quantification of the scale's error, that would be plus or minus an ounce or so. So in other words, if this scale tells you you're 150 lb 0 oz, there's a 95% chance that you're weight is greater than 149 lb 15 oz and less than 150 lb 1 oz, and not some other far-flung number. So it's pretty much to-the-ounce precision with this scale. You eat a 6-oz cup of yogurt, and your weight goes up by 6 oz on the scale (to within measurement error, of course); the scale will even pick up your weight loss due to breathing out carbon dioxide and water vapor + sweating/transpiration if you sit for an hour or two without doing anything.The scale is not for the faint of heart, mathematically and scientifically, though, if this idea is appropriately defined. You *do* have to assemble it yourself, and the "ounces" I'm talking about don't appear by themselves on the scale. You have to be familiar with fractions in order to use the comparatively user-unfriendly markings on it (e.g., that one-fourth of a division past two divisions, given that there are four divisions between each pound, would be 9/16th of a pound, or 9 ounces). Also, it requires a fair amount of manual dexterity to control that little slider on the beam with the required delicacy to get the precision I'm talking about -- plus you do have to watch what it's doing when it's coming to equilibrium and not forget whether the beam seemed to prefer the top or the bottom the last time you checked marking division 3 or whatever.So if you're looking for extreme accuracy and precision, ditching your cheap bathroom scale for this one would be a good idea. But if you're just interested in your approximate weight, rather than, say, the contribution of the weight of your clothes to your daily weigh-ins, just stick with a cheap bathroom scale that you can get for $20 or $30 at Walmart. They'll do fine for those purposes.
