Product review (5 stars): Best purchase of the year!
I am obsessed with this product!  The ice cubes are bullet shaped with a hollow inner core.  Production time is very quick, I would estimate 15 minutes.  My water intake has increased dramatically since purchase.  As others mentioned, it does create background noise in our home and it always seems to be running.  So it's likely stressing our electricity consumption, but I could not part with it.
