If you have a nugsmasher mini, you really need this.
Makes pressing much easier.
Works like a charm, but seems a little expensive for what it is. Three pieces of metal without an apparatus to apply pressure to create an awesome pre-pressed mold. You can use your hands, but I found that using a clamp/vice makes a substantial difference. I am not an expert. I just started squishing. I am giving it 4 stars because it feels like a money grab add on.
Awesome, easy to use, perfect size in all
