Excellent socket replacement. This is a great tool pocket wrench as it can do most of the jobs that a full set of sockets will do (UNLESS AN EXTENSION OR DEEP HEAD IS REQUIRED). in the hand! * Also great for holding almost any size nut when using an electric wrench on the other side. in pic 3) it's easier to grip than the dials and little levers on most socket sets.* Tightening the bolts works very well. What I didn't like:* I found it didn't work very well with smaller socket wrenches because the handle is longer than the screwdriver by 1/4 inch, and the "headset" on the opposite end tends to stick under certain ( small) circumstances to be in the way. * If you are using an "inner socket" and the screw you want to work with is near a raised surface, the "outer socket" may get in the way * The sockets are not as deep as a standard -Sockets, using nuts can be a problem. In general I highly recommend using a complete tool bag socket replacement, but with the knowledge that this may not work in all cases and you may need to resort to a socket set. Other things I noticed: My 2.3 photos seem to have some sort of manufacturing defect. I'm not sure what happened there, but mine works fine.
