Quality 5 stars But instructions 1 star. Its an absolute nightmare to make because the instructions are terrible and none of the parts or fixtures are numbered. You have to look at the drawing and go to a reference page to get the djmentions then go measurd the parts untill you find one that matches. Why not just put small sticky labels on the panels and put the fixtures jn labeled packets like every other manufacturer on the market does. And i am engineer by the way !
