Unfortunately I had to settle for a second rail as I have just moved and have no wardrobes. At first I thought it was because it was supposed to do that and would snap back together. looked cheap and old fashioned Youll likely need to do some tinkering to tighten and position it how you like, but in the end it is sturdy and has great adjustability for a regular sized desk. They have exactly the same fit, they are extremely comfortable and dont fall over! Can minimize volume well for media, but when on the phone, you cannot lower the volume past a certain point. We will be looking into purchasing more items from Picnmix. Over the 9 weeks that I have been wearing them, they have protected my feet and have supported my arches and ankles, but here?s the bad? They are only waterproof to a degree. Despite being kind of cheap looking, it does what its supposed to do and assembly was easy. Otherwise, this item performs perfectly for its price point.
