Input: My first three or four capsules worked flawlessly and the coffee is great! For some reason, my machine stopped working well with these capsules, emitting only a tiny amount of over-concentrated coffee with every single capsule I've tried after those first few. I didn't even use a different capsule between the ones that worked perfectly and all the subsequent failures. If the entire box worked as the first few, I would have easily given 5 stars but seeing as how I can no longer get a decent cup out of these - and have no idea why - I am no longer satisfied with this product.

Does NOT work well with Delonghi Nespresso Machine!
