Question: I was really excited to start using it, but then I got it all ready and I go to pump it down and the air stays trapped in the rubber part? Help!
Document: It is easy to use, no real clean up (except rinsing out the reusable kcup) and can be used with the ready-to-go k-cups as well. I can see how this would be great in the office, too.
(Here in "earthquake country" where the power can suddenly go off, it's nice to think that you could make a great cup of coffee to calm your nerves in an emergency. It's a nice part of an emergency kit for me, along with a crank radio and flashlight.) Very convenient if you have hot water at work and want better coffee than the usual "office coffee".
Since this only uses -your- effort to do this, it has a rubber cap that you need to press down on 2 or three times to create the pressurized water that's needed. This would be easy if there was a little plunger on top to push, but there isn't. You have to cover it with your hands and push down -- HARD. I don't really mind doing it, but it does take some physical effort and probably wouldn't appeal to everyone for that reason.
ThePresto 02835 MyJo Single Cup Coffee Makerworks OK with regular coffee grinds, but really does a lot better with the pre-packaged cups (you have to order separately). Personally, I was hoping to use both types in here, but it was a lot of work to make coffee with the grinds this way. Eventually, you start wondering if it is even worth it -- you'll have plenty of time to ponder it as you relentlessly press upon the top to get water flowing!
Then place the whole thing atop your favorite cup and push down on the rubber top. It usually takes me three presses to work all water through.But that's it. And you have a nice hot cup of coffee.I'm currently using this at work as our K-Cup machine died. But this would also make a great camping pal if you're the only coffee drinker in your family.
I think I just did not have the pumper thing on right and had an air leak. Never-the-less, I find it a bit trying and hopefully once I really get onto it, I will love it. However, right now, while I like the idea of being able to use a k-cup without the actual machine, I am tending to stick with my one cup brewer where I grind my Illy coffee and enjoy.
I can fill it with water, pop it in the microwave for a few minutes and brew the coffee. Here's how it works:The detachable bottom has a place for a K-cup. A cup comes with it that allows you to put in your own coffee. The middle section (the clear part) is where you put the water. You can heat water in a kettle or fill this part with water and place it in the microwave for about 4 minutes.
Just got it, fed it a Starbucks Sumatra Kcup, great coffee easy clean. Perfect for the road, and as I am the only coffee drinker in a tea house hold eliminates a pot on the counter. Recommend. If there are any issues in the future I will revise my review
I suppose this would be a great application for certain circumstances but just not mine. It really is not a coffee maker for a quick cup of coffee,
omg!!! just what I needed, we have the 'village' coffee maker at work,but our lounge is 1 floor up and so many times I needed a fresh cup and was lazy to go down..... so cool!! !, no effort at all, no build up,no ''need to wash'' after taste
Answer: There is a silicone valve, in the upper reservoir, designed to keep water in when no pressure is applied.  That valve has a slit that may not have been fully opened during manufacturing.  It is a simple fix.  Take the valve out (something you'll do from time to time for cleaning anyway) and pinch it to make the slit open.  Once you've done so, re-insert the valve and you should be good to go.
