It’s def functional. It looks nice and is not an eye sore. Def will be easy to maintain for cleaning of dust. HOWEVER, four stars simply cause it is a bit top heavy. I will have to find a solution to weight it down so it’s not so top heavy. Possibly in the future they might design a simple one like this with a simple one pound weight across the bottom.
