I purchased this from Docc awhile back and it is a great tool. As in all tools there is a proper
place for it's use. This little device works well in intamate settings were billet switching may be
difficult - this fills the bill nicely. Will you use all the time - no. As one reviewer said it is
the principle you are purchasing - you will have to provide the application. Can it be used in walk
around - yes in certain settings. I am a big Fan of Docc's material. This is a good tool to have
in the tool box. The secret to using this is to put it into proper context of what you are doing.
