Nice quality especially for the price.  Definitely better than those run of the mill hardware store closet sliders.  Heavy solid MDF boards and nicely frosted glass.  The hardware is good too.  Slides great and will not come off.  Easy to install.  I am using as room separator door so you can see the hardware from the one room but we may just put a piece of molding across the opening to cover it. The picture may look off white or yellow but it is white.
