Ex Input:
I have three Newfoundlands so we go through a lot of food!  One of the dogs has had severe health issues and since we've switched from commercial kibble to home made food, he's thrived!  He gets regular blood tests to monitor the drugs he's on and they have been perfect since we started on Sojos!  It will not cure his issues, but he has more energy and he can't wait for meal time!  The other two are glowing with health as well!  All three dogs coats are shiny and they have tons of energy (for a Newf!)

Ex Output:
5


Ex Input:
Work well and made solidly.  For whatever reason the Keurig takes longer to complete the brewing cycle when using these cups and the liquid bleeds through the filter on the outside of the cup making a small mess.  They do the job as intended but could use a different type of filter to make the experience less messy.

Ex Output:
3


Ex Input:
For product to work properly (IMHO) you need coffee ground as fine as possible. Once filter has been inserted, plave carefully leveled measure of coffee in it. Manuever lid into place, then press down on center-STEADILY- w/ thumb.  Plan to use no more than 6 Oz. of water for your cup.  Removal of used cup from machine is occasional problem. (Jiggle it and it will generally loosen up.)
