I bought a Centech for my FZ1 and hated it. Very dumb design IMO. To attach something, you had to remove the cover to get to the screws. Plus, ground out of one side, power out of the other. Depending on how it's mounted and how permanent that it, you may not have accces to both sides, or be able to remove the cover. I told my brother why I didn't like it and sold it to him at a loss. Plus, it had a bare circuit board on the back side, just asking to short something. Whoever designed that thing must have never used it. Just one man's opinion.
