Query: Bad scale

Purchased from an instructor in a class I took. Did not work out of the box. Called the company-returned the scale. After paying for shipping, insurance, they refused to accept the scale. Called again--they described a process different from what was on the warranty. Considering it would cost me another $15 to send it across the country, I opted out of the worthless piece of junk. There was no sorrow on their part. I noticed when I unpacked the box to throw the scale away that there were pistachio shells in the box. I did not have them there when I sent it and it appears that they opened the box, read the letter and invoice, ate some nuts and returned the scale and the nut shells to me--figure that out. Don't buy one.
