Super simple, looks great on my ceiling. I would just stick with play shoes for these. This is my first pair of Rockport brand shoes/sandals and they are definitely well made and comfortable. Instead, I installed PEACE (search for "peace equalizer") and used that to reduce the level of the lower frequencies. Natürlich muss ich das Teil zusammenbauen und das bedeutet ich muss schrauben. Hes very happy now, they did what they should. Recently I decided on a DIY solution-- Found some 2" diameter furniture feet on here that have a screw hole in the bottom. Im now able to lie down partially on my side. Used it for sunglasses. Im sure if I was using this a little bit more continuously that I would have to charge it more frequently.
