Never heard of them...... After looking it up, I'd steer clear of the "economy" models. They look like they might take proprietary cartridges, which is where they will make their real money off of you. If your serious about getting an RODI
, join in on one of the upcoming BRS (Bulk Reef Supply) group buys and get one there.
And it doesn't speak well that I couldn't even get to Grosite's web site (grosite.net)..... BRS is well known in the community, and their customer service is second to none.
