Medium stiffness
Not the sturdiest bristles (they permanently bend if you set it brush side down for more than a couple of minutes), and I wish the handle was a little longer, but otherwise good- and likely the best you will find for the money. The bristles are a nice medium stiffness, not too hard that they scratch but stiff enough to actually scrub.  Even my mother, who has very thin skin that breaks easily, has no problem with these.
