I ordered the circupool RJ-20 salt water generator. It took them a month to ship it, after I called twice to inquire what was taking so long. They finally shipped my order. When I opened the box the cell unit was a RJ-g model not the RJ20 that i was expecting. They don't even advertise the RJ-g model on the web site. Does any one know if the RJ20 and RJ-G models are of the same quality?
