Dang Bear, you sound like an advertisement. I like mine too--all in all a plus but here are the problems I have had. 1. All buckets really need to be checked seperately for ph etc daily. Thats 8 buckets to lift out every day.
2. very easy care at the beginning when the plants are small but as they get larger into flowering unless you have lots of extra ground tubing things are not easy to move around and change. I ended up putting little stop valve things on all my buckets to shut off water flow and change them (that's actually two stop valves for each bucket--have to stop water flow from both directions.) Very time consuming to empty and change, everything flows by gravity, the res is heavy etc. so draining the sytem takes quite a while but I speeded this up with a little aquarium pump that sucks the water from the main tube (not the res) very quickly. Please keep in mind that this is the only system I have used so I cannot say whether it is better or worse than others. All in all I do like it and it has grown me some kick ass weed. Others on this site with more brains and experience (like the two above) may have answers to the problems I have which I would love to hear myself. I would buy it again. The end.
