Because of some critical reviews here I have long wondered whether I should order the cooker. But I wanted to try stainless steel instead of aluminum and a minor in addition to my stove for 9 cups (of Cilio). I have to say: It was worth it. The stove looks very nice; the material seems to me more valuable than at aluminum. And most of all, the coffee really tastes so great! I think it tastes better, as with my aluminum maker. I could not see any sharp edges and otherwise not detect any problems. The cooker can be attributed to good and to screw. Also he is relatively soon cool, so you do not have to wait hours, if you want to make a second layer. I can only recommend the kettle! (The price is OK, too.)
