Review on Keurig My K-Cup Reusable Coffee Filter | Compatible with All 2.0 Keurig Machines | 1 Count, Black by Christopher Theriault

YAY! I broke a spring in my Keurig filter holder and the SoloFil reusable I had stopped working. That solved all the problems because the "nozzle" used on the Plus models fills the space perfectly and Keurig doesn't say "Oops!". the message is larger (the chip is in the cap). For those who say it doesn't work, I'm assuming you're not polishing the course enough. I grind myself and need it almost as soon as possible (remember the French press). If the grind is too fine, it won't push through the water. If you fill it too full it won't work either. Coffee expands when wet, so do not fill above the maximum line (see instructions). Also, the mounting option is for carafe models only, you don't need the app if you don't have one with your machine, but keep the attachment in case you upgrade. Remember this reusable filter is the size of a travel mug. It's not a good Kraft carafe, but Revain has a reusable carafe filter.
