Bests & Worsts Reviews from Amazon

Having designed electronic measuring equipment I tend to be a bit more picky about my bathroom scales than the average customer... I value linearity, accuracy and repeatability (even if it doesn't matter that much if my weight fluctuates by a half pound here and there) This scale sure is a pretty thing and has incredibly easy to read numbers (The 3.5" is a misstatement, the display is 3.5 inches -wide-, not high. The numbers are comparable to other 1.3" high scales) The "tap to wake" is a bit inconsistent; sometimes it takes a subtle tap, sometimes a sharp thumping with a foot isn't enough to start it up. Not a deal breaker but enough to lose a star in my rating. By my testing the scale is accurate within my typical weight range and very repeatable but watch out for the "fake repeatability" that's typical of scales in this price range: If you step on the scale with a weight that's pretty close to the previous reading it'll give you the same number. Here's a simple test: weight yourself, then weight yourself again holding a half-pound can of food. The scale will show no change in weight. Now step on holding a gallon of water and the scale shows a seven pound weight gain. Step back on holding the can of food and the scale now registers that extra half pound. Put down the can and step on one last time - the scale will again show the weight as if you're still holding the can. I have no idea how long the scale "remembers" the last reading or how big a change it takes to force a new reading but if I want to make sure a small change in weight is accurately measured I make sure to step on extra-heavy or extra-light (put some of your weight on a nearby countertop) and -then- step back on with the weight I want to measure. Again, please note that this behavior is not specific to this scale; most in this price range will show a similar "repeatability" feature.
