unit came on time , but im so sorry i baught this item it is made of cheep plastic, it fell apart before i finished puting it on the walli took a chance and thaught it would be ok,but not in this case i lost out! it would not deflect the heat all the way i took my drimell and sanded it in the corners and noticed it was just bad construction. the idea is good just needs a lot of adjustments its a good thing i do have a background in repairing broken things ,but if you dont know how to repair things dont get it!!!!!
