Very easy to hang.  The electric cord was already aligned to one of the chains, so easy to hide.  Took only 45 minutes - one person - to hang all the glass crystals.  The hook on very easily.  I highly recommend this product.  We have it hooked to a diner switch which was already in place.  We are using white LED lights which when dimmed allow for a gorgeous glow.  Very high quality for the price.
