Query: This is a necessity to my life now!

I work as a barista at a cafe, we use these for our coldpress coffee. So right off the bat I obviously know how to use it. Though I think it's simple enough so that anyone with a brain could do it. I bought one for myself and I constantly use it for espresso. It is a bit pricey but it makes up for it after a while considering all the money I save on coffee. Definitely recommended if you dig iced coffee.
