Useful but not the end all be all.
I have owned this set of drivers for about a year , they see steady work in my every day use in auto repair mainly so I have an excuse to use them. As far as quality they are fairly well made, and the screw driver tips are somewhat softer than one might expect, not peanut butter soft but softer than say a snap-on or other comparable tool, this is actually to help reduce the likelihood of you stripping out slots or otherwise butterflying them (from my experience anyways , it gives you a heads up when you're applying way more torque than they like ) Over all I love these drivers and recommend them for anyone who doesn't own a set of parallel ground drivers.
