I have a very long walk-in wardrobe which I was finding difficult to get a wardrobe rail for with the right amount of support for ALOT of clothes. I wanted 2 rails and I was looking for £30 per rail. I came across this item and figured it'd be good to try since it would go very long and offers 4 rails. Building it was very easy but, I was concerned about it being able to take the weight (I've broken 2 wheely rails which I was using on a temporary basis). My space is 4ft wide and 7ft long. It spanned out into the entire space, I could alter it to the right height and width, the rails are sturdy and have not slid down the poles, despite the weight I've put on them. The poles from roof to floor have not budged. I highly recommend the product, really good for the money, get plenty on it.
