Wyze Scale Inconsistent Results?

Super disappointed with the weight measurements on the Wyze Scale. I can hop on/off several times and get readings that are +/- 1-2% each time. I have it on a hard surface, so no issues there. I would think that it would be exact within seconds of weighing again. I haven’t paid attention to the water and other measures, but have noticed they are different each time as well. I ran through the calibration process (tapping the scale and letting it zero out).

Is this just what I should expect?
