Product description
There’s not much to these things. They heat the dual layered logic boards, like the iphone X, XS, XS Max, 11, 11 Pro, and 11 Pro Max, so that you can separate the two logic boards and repair them. The heat is preset to a temperature hot enough to melt the low melt solder connecting the two logic boards, so there is no need to adjust at all. I was uncertain about the effectiveness of this pre-heater, but it works well.
