Any concerns using Smart ATO (RO) as an ATO???

[JTP424]

Sounds silly, but I ended up picking up some Smart ATO brains and their pumps for super cheap from coralvue warehouse deals or whatever it was...
The system is technically built to refill an RO, but from testing it will work for their pumps as well...
Can anyone see any major issues? (Beyond issues with the product itself ;))
