Query: OK...but not great

I have owned this grinder for less than 3 years. I use it 4-5 times a week on average. I grind only for myself.Last week I pushed the grind button and it disappeared inside the grinder.I sent it to a certified Krups repair and was notified that the parts necessary to repair were no longer available (remember it is less than 3 years old and this model is still for sale).I would urge potential buyers to shop around and spend a little more for another manufacturer.
