For those of you who are into making burgers and want them to come out uniformly or in portions due to dietary reasons, this is the best choice you have to make as it is stainless and the minced meat does not stick even the minced chicken meat. Place non-stick paper underneath, put the ring on top and depending on the quantity of minced meat you want either fill it up to the middle and you will have a burger close to 100-120 grams or a whole one that will have a burger 200+ grams or put the minced meat you want to push with your fist or fingers inside to catch the sides, put whatever you want for filling and put the remaining quantity on top to "close" the burger, push again to "bind" and all you have to do next is to lift the ring and the burger will be ready or lift the ring holding it from underneath and empty the burger in your hand or where you want to cook it. Do not even look at anything else that is not stainless, you will just waste your money. If it had a corresponding press, it would be worth 10 stars.
