Adding DI to my RO system

So has anybody seen these? I was looking for another 10" canister and resin and came across this. I could just hook this on top instead of drilling more holes and installing the brackets for another filter housing.

Don't do it!
Spent the extra money, and buy a vertical unit with better di beads. I had a ro unit from that guy, and had to replace everything to get 0tds. Once I got my filters, and di resin from Bulk reef. 0 all day long.
And those little horizontal di housings hold about 1/3 what a vertical does.

Horizontal is a waste, and one of the many reasons most of the "ebay special" RO/DI units are horribly designed and a terrible waste of money in the long run (arguably more expensive than buying a correctly built unit and high end filters in the first place).

Most of the RC water sponsors have quality DI add on kits:
