Great little gadget, but time consuming. I made various types of burgers, a 110 in all for my family meal ( I have a large family ). Perfect burgers,that dont fall apart. The only downside is that it is time consuming to make a larger batch, but good to freeze, provided your meat had not previously been frozen. Make sure you take apart fully to clean, as meat gets trapped inside. Have recommended to a few people.
The discs are great for stopping the burgers sticking together,but remember you need 2 discs per burger, so they dont last very long if you making a larger quantity. would recommend, very usefull. I have used 500 so far, but that is for 250 burgers.
