Lone Star Grillz Warming Oven

I am looking at getting a new vertical offset from Lone Star Grillz and had originally passed on the idea of getting the warming oven option they offer but now I am thinking I may get one. So the questions I have for those of you on here that have one are do you use your warming ovens very often, what range of temps can you get in the oven, and what kind of things are you using it for? It seems like you could get rather creative with uses for it.
