I don't know, but the next time we need a single use coffeemaker, we will be giving serious consideration to other brands - maybe go with a Cuisinart, we'll see. We bought a Keurig Supreme Plus close to two years ago and we are on our fourth replacement. The most recent replacement prior to the one we're currently using wasn't even in use for three weeks when it konked out. Keurig made an exception and replaced it but told me im maxed out on my replacements, so the next coffeemaker will be a new purchase.
