Torus Perfect pH

I'm looking at getting the Torus Perfect pH for my DTW Coco.

It apparently keep your pH in the 5.7-6.4 range without the using any pH up or down.

Anybody using this system already?

I had a few of these units to test out last year in my rdwc system.
They definitely kept the ph very stable but I did see some weird growth in my root system compared to previous grows.

I'm running them right now they work. Can't say I noticed weird root growth though and I'm running rdwc
