Not very comfortable
I wanted to enjoy this but I just don’t unfortunately.  It doesn’t fit my neck very well.  I try to adjust it with the straps and I just can’t find a comfy spot.  Same with my back.  Really the only place I can get it to somewhat fit ok is my leg.  I can’t really say much else as I just couldn’t use it as intended.  It’s a fail for me.  I gave it 3 stars as it does everything it says it does, it just doesn’t fit me well.
