If you love soaking up pools of water from your countertop and floor every day, this coffee maker is for you! 
The markings for the amount of water needed for each carafe type is not accurate so you are always left with water in the reservoir (I fill only to the amount I intend to use, I do not overfill) which ends up leaking out onto the countertop. I spoke with Ninja support about this issue and they admitted that this is faulty gaskets. I've also seen this commonly reported in other reviews so it seems to be a glaring problem that Ninja is unwilling to fix.
I rated 2 stars because the coffee is good quality and I do like the size options, but I started having problems with this machine within the first year. I previously owned a Ninja coffee maker and was impressed but won't continue with this brand after this issue.
