After a long search for a silicone case for my Galaxy S II with the larger battery Samsung original battery pack with rear panel EB-K1A2EBEGSTD (compatible with Galaxy S2) in black, I came across this shell and to my amazement and enthusiasm fits this perfectly here! All outlets are protected but easy to grip, although the mobile phone looks a bit massive but grippy and light purple tone like it very much! Occasionally I take the envelope from but to clean the edges, because it always collects dust at lighter shell edge. Since the shell but can well remove and install again, this is absolutely not a big expense. For me, just the perfect case!
