Query: Poor Design

Water tank needs to be removed to be filled, even for 1 cup and at that the flap on the tank is awkward making it difficult to fill.The clasp to secure in the pod is poorly designed. It jams at times and at best is hard to secure.The amount of water going through the system varies at times for no reason.The design issues make this machine a poor choice. The quality of the coffee is ok but I find that true of every coffee machine regardless of price. I like coffee but not a snob about it.
