I have now used three different methods to make cold brew. The Toddy is very difficult to use. It is messy. The filters have fallen out more than once causing grounds to get into the coffee and the force of the coffee to shove the tiny cheap stopper out and coffee spilled everywhere. I don't actually understand why this system is so popular or why it costs what it does. It is made of cheap and flimsy material. I would gladly pay a bit extra for a cold brew system that does indeed work well but I have not found one yet and this system is not it.
Cheap, Messy, Just Use a Filter system if you want to go this route
