We like our R-Can Sterilight scm-320-dws22 Cobalt Plus system. The instructions were very straight forward. My husband built a shelf to mount it on the wall as space was limited. The only issue was the instructions showed a spacer to be between the bottom of the UV light and the canister, we could not find it. He still made it work and all seems be doing well, but we have not had our water tested again to be sure.
