The cushion inflates the price of course, but the use is roughly practice. It is on my desk. I use my phone, I top rests with ease, neither seen nor known. Biensur not suited to all situations (basically at home or in a fixed location, office, etc) but it is much, much more ergonomic than plugging a cord.
We put on the cushion, it load, end of story. And no slower than a cable. Expensive but still 5 stars.
