I've already tasted a number of different coffees. They are tasty, with a little foam on top. A dozen or so guests have already tasted the coffee and were satisfied, though not very complimentary... The machine's strong point is, of course, zero waste: the balls go into the garden to control ants or into the compost bin, and the cardboard packaging too. It's great to be able to drink coffee without having all that packaging and capsules to recycle! The machine is easy to use, if a little noisy, but that's acceptable. The capsule recovery system works well and is practical to empty, although a small notch to pull out the recovery system would be more practical, but that's a detail. In short, this is a good coffee machine that respects nature and allows us to limit our waste while enjoying a tasty cup of coffee. The price of the coffee balls is still a little higher than some other brands, but for the average consumer I think it's still worth it, not to mention the savings on waste disposal, which makes it worthwhile to pay!
