I like this switch box for having everything for a CF based saber in one spot. The difficult part was drilling the necessary holes through the saber body since two of the components are off center. It also did make it a bit difficult to get everything to fit, though I should have used the smaller battery to help make some extra space. I did have some issues with threads that weren't sufficiently tapped, but I let the shop know about it so I don't expect it to be an ongoing issue.
