I dunno about you folks, but for me, I install the hack if it is useful for my site,
regardless of what comments are posted previously, because over the course of my time here in vb.org, I have come to realise much of the problems posted by those who installed a hack, are often due to their own faults at now reading instructions properly or applying fixes already posted in the hack thread.
So I just go ahead and install it and if I face a problem
personally, i either seek help in the hack thread, remedy it myself by looking at the code or just uninstall it if it is beyond me.
my 2 cents
