Is this a disposable unit? Very neat.

You can replace the DI cartridge which is about 85% of the price anyway. It is essentially a DI filter and it works great on our low TDS Vancouver water. It is perfect for the smaller tank around the Lower Mainland. I used one for years on my 46 gallon. You'll need a bit of patience for anything larger.
Be aware, however, that unlike a full out RO/DI unit this thing cannot deal with turbidity and particulate matter very well. I often found that its output slowed even before the DI beads were exhausted because its small foam filter pad was clogged. And unlike a modular RO/DI unit everything is in one single cartridge that you have to replace in one shot.
I was also wary of the city injecting extra chlorine into the water after a heavy storm since it can ruin DI beads. On a full RO/DI unit you've got multiple layers of protection to deal with extra chlorine before it gets to the DI. On this unit all you've got is a thin layer of carbon, I think.
I know that OA used only DI filtration for quite a while when they started up, so this is a good way to go until you upgrade to a bigger tank.
