Some scientists brewing herbs for research found Nespresso machines to be almost perfectly efficient. In my work with residential maintenance I find Nespresso machines extremely common but also frequently broken. They are not easy or cheap to repair so often there is an upgraded unit which also breaks. This raises significant issues with durability and design for disassembly. Going for cheap with a high end product may end up cursing the line over time. What I find enduring are the older type of Cuisinart brewers which are made of relatively robust components that are easy to replace. They are nowhere near as good but endure actual use much better.
