i like it. its not bad. for the price i bought it for it was great, which was like 30 bucks shipped and new. it does what its supposed to. i also have an UltraLife flo switch, which i dont like as much but it does its job too.

if youre worried about corals being in contact with the ro/di, try to see if you can place the outlet near an area where there's high flow, or in your sump like i have it
