It is a pretty low quality drinking water system at best. They can be found for not much more than $60 new on e-bay. For a good quality system that will truly give you reef quality water andhave the components you will want and need its going to cost you right at $150-$160 new. Any less and you give up water quality, component life or both.
Good systems will come with a true DI filter which consists of a standard sized 10" vertical canister with a refillable cartridge that holds 20 oz of high quality DI resin. Also a Dow Filmtec 75 GPD RO membrane is the industy standard due to its 96-98% efficiency unlike that ones 90% efficiency.
They will also include a handheld TDS meter, an inline pressure gauge, a prefilter in the 1 micron or less range, a carbon block in the 0.6 or 0.5 micron range, a RO bypass valve...... The list goes on and on and not one of the things I mentioned is included in that one. Even if you were to get that one for $60 you will invest more to bring it up to reef quality than if you spent $161 on a new 75 GPD here.

There are several more RC sponsors that sell very similar reef quality units in the same price range too.
Take a look at the link you provided, notice things like they do not tell you micron ratings of prefilters and carbon blocks? Notice they do not tell you what brand, manufacturers model number or the efficiency rating of the membrane they supply? They do not tell you what brand or blend of resin they provide nor how much the little hollow tubes hold? All those things should be big RED FLAGS meaning stay away or buyer beware. Look at all the RC sponsors units, thye tell you right up front what you are getting, no false claims no BS just the simple truth. They all use name brand components that are proven products with a track record.
