I have one of each version. They are OK but tool to size ratio is not great. The thing that was most appealing to me was the big knife blade and OHO on all tools. The pliers work OK. I did like the screw drivers. Buck did discontinue the X-Tract and as they were imported I think the China manufacturer is still producing them under the Buck name, but not for Buck Knives. Not sure of the quality of these versions.
For the price they sell for now I think they would be Ok as spare or back up tools.
