The double towel bar kept coming off the wall. Wayfair was kind enough to send me a replacement, but the same thing happened again with the new one (even though we hung the bath towels on the back rod and the bathmat on the front rod this time, thinking it might be the weight). There is a set screw that has to be tightened on the post once you install the mounting anchors to the wall. Those set screws keep getting lose and then whole towel bar comes off.  The same thing is happening to the toilet paper holder.  IT MUST BE A DESIGN FLAW.  Very frustrated with this purchase!!!
