Query: grind select failed, then timer

I bought this item about 18 months ago. After about a year of use, the grind selection failed, and it always produces a rather coarse grind. Then more recently the timer has stopped working, so I count to fifteen and turn it off by hand. This was a very inexpensive burr grinder, and while surely I was unlucky, it was too good to be true.
