I cant say enough good things about these blinds !! Im not crazy about 2 in non wood blinds and Im very picky... Im in love with these, everything was very well packaged, they came very quickly ,the hardware for installation is heavy duty metal ,there is not a piece of plastic to be found anywhere in the mounting system... taking them up and down to paint the windows will be no problem at all , the hardware is such that you install large square metal brackets that are hinged on the front, you slide the header of the blind in and then close the metal latch... it snaps into place . Done. I have zero concern that these guys are going to slide out of the mounts.  For the price you cannot beat these! I would actually expect to pay more elsewhere but of course here at Wayfair theyre incredibly reasonable and the shipping was free !! Five stars all the way!!!
