Review on Perfect Pod Cafe Fill Value Pack - Reusable K Cup Coffee Pod Filters and Coffee Scoop for Keurig K-Duo, K-Mini, 1.0, 2.0, K-Series and Select Single Cup Coffee Makers by Jake Hillyer

Can work with other Keurig? Doesn't work for K-mini. I noticed that the button just behind the pod holder that indicates hot water should flow from the heating part to the spout on the K-Mini lid was not pressed. This is because the lid of the refillable capsule is too high. I tried to fix this by applying several layers of tape to the part of the lid affecting the button in question. It works intermittently, which is better than not working at all, but still almost unusable. As a result, you have to be seated and hold the lid closed so you can actually see it's closed. This contradicts Keurig's primary purpose and only real benefit: convenience. Also, the ground coffee actually ended up in the coffee itself (I used a pretty standard grind size, but also tried coarse and fine ground coffee just to see). And finally the end product was watery and I'm not sure how the coffee grounds got into the cup and then the coffee got very watery. Not 100% sure if it's a capsule issue or an issue with the already pretty terrible K-mini. Regardless, I would consider other options as this one doesn't work. In the past, reusing K-Cups by cleaning them and covering them with a layer of aluminum foil seemed to work well, although not as consistently as a sealed container. That said, if you're looking for a reusable case for another Keurig and it's known to work, at least I think the build quality is good, the price isn't the best, but the scoop that comes with it is actually quite useful.
