More than happy with my RK2. I dont however have any programming brains, so its not being used to its furthest ability. Perhaps not the same as some systems but great for the price it cost me. Been running perfect for over three yrs. now. Only upkeep has been replacement of temp probe and super excellent customer service and web site as someone mentioned.
If I had a new large tank one day again, {not going to happen}, I may go Profilux for a few reasons, including some of our sponsors.
