I had this grinder for 9 months and now the timer function no longer works. To grind I have to hold down the start button. Called customer service and they can't help me without a receipt. When I gave them my model and serial, they claim the unit is 2 yrs old and doesn't fall under their 18 month warranty.I would have given this 4 stars if it kept working. It was a bit messy but ground the coffee just fine.Totally dissatisfied customer.
