It is discouraging but I have not yet gotten up enough determination to ask Philip if these kits are being constructed with factory seconds that failed some sort of quality test that kept them from being distributed in the PRC. Every single kit I have has one quality issue or another which would cause me as a line inspector to pull it off the line and send it to that area at the end of the line where any defects or quality issues are attended to and repaired instead of dumping on buyers located in another country, where they could not find me.
