Hi! I also purchased a Kamenstein scale from Costco. I paid $14.99. I did not use it immediately because I purchased it as a replacement for an Escali scale that was still functioning but on it's last legs after about 3 years of intense use. We retired it to use in scaling chicken feed and I opened and began using the Kamenstein in the kitchen about 4 months ago.
Couple days ago the screen started fading. We changed the battery and now the screen doesn't work at all.
