Past scales I've owned have been useless b/c of lack of consistency. I checked this scale for consistency (shows the same weight for the same object weighed multiple times under the same conditions) and accuracy (although a scale can be consistent - showing the same number for the same object - the number itself may not be correct). Summary: Consistency is within 2/10's of a pound (I was hoping for just within 1 pound so ... this exceeds my expectations) and, based on my holding dumbbell weights, it's accurate. Details (I kept the scale in the exact same position on a hard, flat/even floor w/ no bumps, inclines or declines): Consistency Test 1: 1. Tapped scale to turn it on, got on & weighed myself: 198.4 2. Got off scale, didn't let the scale turn off by itself, got on again & weighed myself: 198.4 3. Got off scale, let the scale turn off by itself, tapped it to turn it on, got on & weighed myself: 198.4 Accuracy and 2nd Consistency Test (this is not 100% accurate b/c these are old, metal dumbbells & they were never checked for how accurate their weights are -- the maker of the dumbbells can have a reasonable margin of error of a couple of tenths of a pound and/or the weights may have chipped here and there) 1. Put 2 25-pound dumbbells on the scale and they weighed 49.6 (issue: difficult to simulate the same condition as someone standing on the scale) 2. Let scale turn off by itself, tapped it to turn it on, got on scale holding a 30-pound dumbbell: 228.0 (4/10's lb difference based on Consistency Test 1) 3. Let scale turn off by itself, tapped it to turn it on, got on scale holding a 20-pound dumbbell: 218.2 (2/10's lb difference based on Consistency Test 1) Final Consistency Test (Compare to first): * Using the weights helped to check accuracy AND they helped to simulate someone else getting on the scale so that I could then do another, final consistency check for my weight alone and compare it to the first consistency test: 1. Let scale turn off by itself, tapped it to turn it on, got on scale without any dumbbells: 198.2 (2/10's lb difference based on Consistency Test 1) 2. Let scale turn off by itself, tapped it to turn it on, got on scale again without any dumbbells: 198.2 (2/10's lb difference based on Consistency Test 1) * 2/10's of a pound difference between the first test and this test exceeds my expectations. Notes: 1. I kept the same clothes on (including glasses) and didn't eat, drink, go to the bathroom, etc between weighings. 2. Always first tap the scale with your foot to turn it on; don't just get on the scale if the scale is off (it didn't calculate my weight when I didn't tap it first to turn it on) 3. Scale will turn off by itself after about 15 seconds from last weighing 4. When you get on the scale, you'll see the digital weight number fluctuating until the scale determines the correct weight and then it will blink the final number to show that it's done calculating.
