Replacement resin from Filter direct

[BigDora]

Has anyone used the resin refill for their Water General RODI RD102 unit? I just received the 18oz package from FilterDirect. The website says it is good for 3 refills, but it doesn't look like much. Has anyone used this? I also ordered a single refill of the color changing resin from Bulk Reef supply and that is vacuum packed and looks like a larger volume.

The filterdirect refill I bought was good for (1) refill.

I have this same unit.
Does this have the piggy back di resin chamber?

I replaced mine with one of these..

Seems a good deal as it says it's good for 3-4000 gallons, when the original ones are only good for 500ish.

Just looked,I actually have the 106 model#.
I added another DI canister onto my system from Bulkreef.
