It?s really heavy, so make sure you mount it very solid. 5mm fitting, meaning any aftermarket cable will have to be trimmed down to try and get it to fit into the hole area. I had to reduce it to2 because it broke so quickly. Definitely returning. I bought these in the largest size. Needed something to fit a small space near the back door for the dogs leash and stuff. This one is completely different and it doesn?t give me that extra butt form like the cheap one from Walmart. They don?t make them like they used to! They?re so cute and still comfy but the only downside is I can?t plug in my charger or headphone cord without taking these off. All the pixel animations and pictures are free and shared via the app.
