I purchased one "set" of these, which was actually 4 tie/hold backs.  The pricing  was rather remarkable (I had to call to verify that it was actually two sets of two!).  The quality is not top-of-the- line; they're very light weight and the finish is easily scratched if you're a bit careless.  But holdbacks are not 'moveable objects', so once installed, they work well and look very nice.   They match my other oil-rubbed bronze pieces.  A real plus for me (since I do all installations on my own) - the hardware provided was complete, with nice, finished screws, and anchors of the appropriate size.  Also, the finial will unscrew, making accessibility for installing them very easy.  I would absolutely buy these again.
