Familiarity: I've used it several times
I love this shoe! I've owned several pairs over the past 4 years and they are my go-to aggressive pair; perfect for bouldering. They have a very stiff toe edge which makes standing on small foot holds easy, they aren't the most sensitive shoe fresh out of the box but once they are broken in I find them effective.
My one complaint is that the strap breaks well before the rubber wears out, which is frustrating when I am putting them on and trying to get them tight. However if you want to put the time in to sew them they will work great again. Overall I highly recommend these shoes if you are looking for a more aggressive pair.
