Mine sat in piles of MDF dust down in my basement/ workshop for weeks during construction of my cp and cab. However, it has been in use since April 04' without any problems.
Its use should be considered minimal, but I think it would be somewhere between light-normal use by others here. I have only played a few heated games of golden tee on it so it has not been abused much (besides the MDF dust thing). I have not heard from anyone else either regarding its poor reliability.
