Would this RODI filter be ok?

I have no idea what i should be looking for exactly but i know a 4 stage is good enough for my cities water.
How does this one look?

It looks fine but you can get a 5 stage from BRS for the same ish price.

I am making the assumption that you are in Australia since you posted a link to an Australia company. I saw this brand posted on a video a couple weeks ago www.reefpurero.com.au

WOW! Parker, sounds like your a smart man, BUT I gotta ask, how does the Resin filter/ reactor being after the RO Membrane help protect the membrane?
Why would you even suggest to another budding reefer to use your discarded unit, knowing it is no longer suitable for reef use?
