Testing responsive without mobile device

Question

I'm working on making my site more responsive. If I decrease my browser width to its minimal width, is this a good substitute for testing what will happen on mobile devices?

I don't have devices such as the iPad Mini or Galaxy S2/3 but still want to make sure the site will look good on them.
