+ Practical, lightweight
+ Easy access to the phone housing
+ Adapts well to Xperia SP
+ Buttons remaining accessible enough
+ Attaches to put the son of headphones or key
- A much better light or set the screen brightness max because the plastic screen adds reflections
- Plastic benefit from further glued to the screen (for touch and flare)
- Not really tight, put your laptop in a zipped bag before inserting into the cuff if you run in the rain
