with your Qs
1. i would guess someone in china
2. contact the seller, looks to be a super auto coffee maker
3. depends on what "suitable" means, it will make something but that something may not be classed as "coffee"
best you go and try it out, they are normally "cheap" for a reason..... dont waste money and have a bitter aftertaste in you mouth....
all depends on what your looking for really
