The flat screwdriver tips are not accurately machined, because they are shaped for the prying tool, which makes them less than ideal; but the prying tool functionality is great, as there's no small pocket knife or other little tool I've seen that's suitable for prying - which I seem to need quite regularly. The Phillips end is surprisingly functional. The bottle opener appears quite functional, but I haven't tried it yet. The large hole makes it easy to get my key ring out of the way when using the Phillips tip, gives a good thumb and fore finger grip, and helps it sit well with the key ring in my pocket. The finish is holding up well. I like that it has no blade, so can be carried through airport security. The small size and light weight means that it is comfortable to carry with a few keys, and it doesn't dig in to my leg or cause undue wear to my pocket.
