What kind of work.
The insert bit types work fine, but the tips do have lightly wiggle in the holders.
The fixed type handles are better since they don't wiggle, but if you snap or dull a tip, then you have to get a whole new driver.
Really, for hobby work, an Irwin bit set with 1/4" hex hand driver will be fine.
The tips are not made out of cheap steel that is going to dull quickly, and if you do snap a tip, then easy enough to buy a new replacement tip at say home depot or lowes.
If these are going to be your bread and butter for work instead, Then spend the extra money for hand drivers that have a life time warranty instead. Snap on/ Mac has good sets, and the extra money you are paying for them, thick of it as a free delivery charge service if you snap one, and they need to bring you a replacement.
