My initial thoughts -
I was under the impression that running an ATO directly from your RODI shortened your membrane due to the short cycling. Perhaps I've been misinformed. The solenoid combined with the 20 sec shutoff should help prevent the nightmare scenario of an RODI run ATO overflowing & lowering your salinity.
As to the pump version, it seems to only have 1 sensor although the article implied it also had a high water shut off. Is there a second sensor I missed in the video? Again the 20 sec system shut down is good, but I like having a second sensor as backup.
So, seems ok. At $150 it's a great price if it has 2 sensors. If it has only 1 its more than the Tunze Nano osmolator (although does have an optical as opposed to a float sensor).
Just my 2 cents.
