Our first unit died in about 2 months. It gave no readout. Soehnle replaced it with a unit that failed to work straight from the box. The third unit worked for about eight months and now also gives no readout. The warranty is 5 years, but still. Here is the usage that led to multiple failures: the scale sits on the bathroom floor, and we collectively weigh ourselves maybe 4-5 times a week. We stand on it, get a reading, and step off. And it has broken 3 times with this hardly strenuous usage. The glass is of high quality, but the working section is made of cheap plastic, and apparently poorly engineered electronics. I have never had similar problems with much cheaper electronic scales.
