From Amazon a Verus Iron bumper £14.99 in red
and a Seidio Tetra metal bumper in silver £20.81.
I use a soft sun glasses bag as a sock and i converted a screen protector that i already had so they cost very little.
$15 dollar clear case as an act of desperation when getting the phone. It was garbage. I replaced it with an Elago case from Amazon for $10. Surprisingly the cheaper case is better.
