The thing to buy with his coffee: economical, durable and easy to use. For excellent coffee and without sacrificing nature (not always so good filter papers they sometimes leave a funny taste and are anyway not very green). The economy is real which does no harm. This format is well suited to the standard norm, throw the coffee grounds (or keep, depending) and rinse before the next use. Simple and effective. I recommend and the principle and this model that I probably would buy.
