I use this at home for my morning coffee, and I've taken it to work a couple times as well since we've got a really subpar drip maker there. You don't have to buy an expensive burr grinder to make a great cup of coffee with this, nor be super precise about the water temperature, as it's very forgiving. I use a normal push button electric blade grinder, and grind my beans to a medium coarseness, heat my water to a boil in an electric kettle, then let that cool about a minute. Pour a little water in to get the grounds to blossom, stir ten seconds, add water about halfway up the chamber, stir, let it sit a couple minutes, pour a little more water in and stir, then press slowly. Does the trick for me.
My comments on this time as to build quality are overall very positive for the maker itself. Remains to be seen how well the rubber (or rubber-like material) on the plunger holds up. And the little case to hold a handful of filters at a time is kinda poorly engineered--mine doesn't stay closed. Small gripe considering the price, convenience, and quality of brew I get from this, but annoying nonetheless.
