The material of the slats seem ok, I'm hoping they are UV/Fade resistant.....time will tell. Big disapointment with the plastic hangers....they have been fitted in the sleeve where you cannot slide them out unless they break, which they will because the plastic that they hang from is wafer thin and 1mm deep.....my old hangers were 4mm deep. Then when it comes to replacing the hangers....will you be able to find ones that fit the sleeve? and if you do, you will probably have to replace them all because that slat with a new hanger will probably fall at a different height to the rest. Also when you order and you are given the option of Chained or Chainless weights, don't expect to get a weight without the protruding bits to fix the chain on. The weights are exactly the same, so a little mis-leading. Should just state, do you want your slat with or without chain. A weight without those protrusions if you don't require a chain would look so much better.
