Come al solito, spinto dalle recensioni (ma soprattutto dalla sezione domande e risposte) ho acquistato il suddetto modello di stativi. The next day my wife used them with her phone and when I paired back to my phone the volume in the left ear was much lower than the right ear. Happy to say everything came in good condition. Aún así, el sonido es sorprendente y los compraría igualmente. My truck could dislocate a vertebrae when you hit railroad tracks so this was important my phone doesnt get bounced around. My only complaint with the keyboard is the lighting. She seems very interested in it, but hasnt had a chance yet to spend a lot of time playing with it. Ill be curious on the prolonged battery life, but charging is fast. Cons:-The CD Rom "Eject" button is right above the delete key, which is easy to sometimes hit by accident, which becomes annoying at times. If a child did not make this, then sorry developer.
