Bests & Worsts Reviews from Amazon

I have owned this scale for nearly a year, and I am disappointed. The good points first: it is inexpensive and easy to set up, and the cat can use it to weigh herself with no human assistance. This is endlessly entertaining, and I now receive almost daily updates on whether the cat weighs 11.2, or 11.4, or only 11.0 (immediate infusion of tuna fish required). On the other hand, I have found this scale pretty unreliable for weighing myself. It needs to be calibrated at least three times a week. My bathroom floor is slightly uneven, and this may be part of the problem, but what person who is buying an inexpensive bathroom scale really wants one so sensitive that it can't be used in an ordinary home with minor imperfections in the building? Also, the scale skips around--sometimes it reports weights that I know are about 10 lbs. less than I actually weigh, and sometimes it reports weights that strike me as 1-2 lbs too high. I can weigh myself three times in the space of ten minutes and get three different weights spread over a 10-12 lb. range. While the scale looks good, I find it far less reliable than the cheap, cracked, 15-year-old bathroom scale that I unfortunately threw out last summer.
