Generally the Temple Audio system is very nice, i would say in the case of the power module tho i have a concern that the screws by which it attaches to the end wall of the board are very small and there are only two of them. The instructions caution against over-tightening, presumably to avoid stripping the threads of the screw-holes in the pedal board wall. The result does not feel sturdy.
I believe it would be much preferable to have either more screws or, preferably, bolts that go all the way thru, obviating the danger of over-tightening and providing a strong connection. It wouldn't surprise me if i had to make this modification myself eventually.
As far as the functionality of the module itself - it's fine, does what you'd expect. Not the best aspect of Temple Audio system, tho.
