I have killed two Gecko's to date and was able to fix one but not the other. It was a fairly simple change out of the main chip if I recall and it would have had to have been easy as I am definitely NOT an electronics type of person - arc welding is about as close as I normally get to electrickery.

With my 50% success rate I also have a good home for any dead geckos that are no longer wanted by their owners.
