Here is the cause of folks mis-fires on this mod. Its not a mystery. I'm simply showing folks that may not know what it is and how to fix it.
Here is a picture of one of my connections after 3 days of (Evening Only) use.

Sorry, My cameras are not setup for Macro Shots. But you can see the black oxidation created by the arc when the button is pressed.
This cleans off very easily (for the time being anyway) but is causes random misfires.
After cleaning, the button works with a gentle press. However it should be noted that the "gentle presses" can cause this to happen faster due to the resistance between the contacts. A nice firm, not crazy hard, press is better in the long run.
The bottom line is this clone will require constant cleaning of these contacts to keep it preforming as it should. Overall, its a decent little mod.
