i bought this unit knowing its limitations as to accuracy and temperature scale (F-C), but I cannot believe you can ship something like this all the way from Hong Kong for the price!!  Yes it was a bit slower, but then it was exactly what I needed and the shipping was free!!!  what I really love about it is that it is designed to fit into a square hole and lock in place with no visible edges showing.  really perfect for an install where you want a real professional look.  I am going to put it in my Sienna and had thought of using double sided tape but now I will cut a hole and properly mount it.  Win, win all for such a low low price!!
