So all a "breakout" box really does is just that; it breaks out (apart) the pins from the connector into terminals you can connect your floats to. There's no real electronics contained in it; nothing to "trust" per se.
Provided you use some floats of decent quality, clean them at regular intervals, and have some good logic programmed into the Apex outlets, it's just as good (can be much better) than any commercially available ATO system.
