Pros- I love that it doesn't sweat, it holds its heat so well. I was paranoid about trying not to overheat it so it got some getting used to but it's super easy. It doesn't smell. The front is so super soft Cons- the back isn't soft, the straps you can't remove for when you want to use it in bed. The hottle moves around in its covering a little as there's a bit of space where the canvas starts for it to move to. Ideas- a second covering I can put on to sleep with so I don't have the straps flapping around. Soft on both sides. It would be great if they made a attachment that connects a second hottle to the straps of the first so I can have heat front and back at the same time. All and all I would recommend to friends and family but would love to see some of my suggestions made as the straps really annoy me when I'm in bed and that's where I want to use it 50% of the time.
