His good: Inexpensive; holds well on the arm without the need to overtighten; flexible material pleasant to touch; size perfectly suited to the Galaxy S2; no pb to use the phone.
What I like least: I have a screen protector on my like, suddenly plastic window cuff sticks to the screen and I galley each time to get out. If I too force, peeling off my screen protector.
It lacks a small isolated pocket for car keys, for example. Y has a little thing that looks like it, but too small for our key "modern"!
(When the dealer, Novago are really pro: fast and efficient small concern on another product, service exemplary.!)
