Query: Great for skinny arms!

When I ordered this, I was worried it might not fit my arms (I'm extremely petite--the size of a 12-year-old kid) since none of the reviews mentionned the "minimum size". I was pleasantly surprised when I received it---it fit perfectly..and it can even go smaller if needed. It's very comfortable and it holds my Sony Network MP3 player (the round one) securely. It's a bit big for my MP3 player but I use the extra room to store the earphones. It's a good buy.
