Mel-Mans contributions to this book alone justify the cost of this book. The noise cancelling is just as good as with the larger versions and in some cases better as they dont shift over your ear etc. I dont like that the back heel enclosure area is pretty much worthless as it has no structure to hold your foot in the slipper. It doesn?t work if you put it in the way it?s intended. The fur isnt really soft and feels kind of, polyestery, but I wear socks, so no biggie. This is a great shoe, good quality and durable. I buy most of my shoes ?online? and seldom have a problem with a standard size 10. So far I mostly use this at bedtime so I cant speak to just how fast it charges. Head?s up - there may be some sort of design flaw here in this particular shoe. It?s too small to hold standard sized men?s 15-16 shirts on either shelf so your newly ironed shirts are going to be wrinkled.
