5 stars because how they  looked when all done..
BUT, these are time consuming  to assemble..advise 1st- screw extender rods to crystal  wires..I bought the 24 flush mount. 2-Work around top of fixture down. 3- place bulbs in . 4 finish screwing  rods in.  4- cut zip ties.. 
I stayed on ladder while sis handed up rods..very helpful.
Looks beautiful !
