Query: Looses accuracy after a short time

When I first got my Tanita scale, I loved it. It was fairly accurate (if I got on and off the scale to check the accuracy, 3 out of 4 times were the same). However, now that I've had the scale for almost a month, it's lost all accuracy. 4 out of 4 times weighed, and they're all WRONG. I not only get the wrong weight shown, but sometimes 0 (ZERO!) as a weight and also Error messages. I would not recommend this scale. It's nothing more than just a glorified paperweight now. Don't waste your money. I would, however, recommend a Taylor scale. I've had one for 3 years now and it's still working accurately. Plus, it was about $20 cheaper than this one. The only downside is that it doesn't have as high a weight capacity.
