Bests & Worsts Reviews from Amazon

I purchased this item and then realized that the wattage was insufficient and I should probably get the larger version. But when I went to return it I received notification that I couldn't return the item. NOWHERE ON THE PRODUCT DESCRIPTION OR INFORMATION DOES IT SAY THE ITEM CAN'T BE RETURNED. To sell an item this expensive and not make it apparent that the item can't be returned is extremely poor customer service to me.
