They need to make it possible to remove the coffee bean hopper, if you want to change the beans to grind a different flavor bean, it is difficult to empty the hopper of whatever beans are currently in the hopper.

The minimum number of cups you can brew is 4, that is not acceptable.  You can't brew just one cup of coffee.  That is wasteful and saving the leftover coffee until the next day defeats the purpose of a freshly brewed cup.

This coffeemaker is constructed mostly of plastic, don't like that cheapens the product.  For those reasons, I returned this item.
