I am not a heavy user of a multi-tool.  I carry them on outings due to their versatility.  I bought a new one as I needed something more heavy duty.  I was very pleased with the SOG PowerLock right out of the box.  The overall quaility is good and it feels substantial.  It has a decent set of tools for what I want and the pliers are powerful. I most often need the pliers, the screwdrivers or the knife and all of those work well.  The scissors seem fragile.  I also bought the bit set.  I don't carry the tool on my belt, rather a backpack or daypack, so it is not a problem for me that the bits don't fit in the same sheath.  However, they really need a sheath as I suspect they would be easy to lose from the plastic holder. For durability and quality, I think this is a great tool.
