Primula Coffee Brew Buddy 

just bought this and it works well. I've let it brew for about 5 mins. Easier to clean than the French press and metal filters.

Looks like one of the better ideas I've seen. Since you are going to use it in your favourite cup, which you fill; You are also soaking/steeping the grinds. The problem with most "pour over" systems (and single brew machines), is the amount of coffee it takes to get a cup. Like 20 gm of coffee, which is costing 4 to 5 times as much as a good instant coffee. Others have commented on using less coffee. You still need the pour over touch though. Slow and to the top of the grinds without overflowing water through the screen. I see someone on Amazon bought one of these with a Melitta. Let me save you the time and money. Melitta has been around a long time and I still have no problem telling you, they really suck. If you like the taste of paper filters, (which you don't taste when brewing full pots) even the expensive brown filters, then you might actually like the Melitta.

Sounds handy, but why can't you give a recommended "brew" time on the instructions or in this video.
