I've been looking for a good alternative to Nespresso-made capsules ever since I bought the machine, which was about 3 years ago, and I'm extremely happy to have found Pod&Parcel! I have a feeling I'll be switching to these for 100% of all my caffeine needs.
Not only do these taste like actual good coffee, which is not something that can be said about capsules from most other vendors I have tried so far, they also produce very reliable output: every single capsule I used resulted in a perfect cup of espresso which smelled and tasted like proper coffee; with other products on the market, my experience was every 6th or 7th gets stuck in a weird way or blocks the nozzles somehow and you end up with a disgusting mess of a drink (as well as wasted $$).
Finally, compostable pods! Now you can both have your perfect shot and be kind to the planet. This makes so much sense, everyone else should be doing this by now.
