Contrary to some reviews, it disturbs the birds not that they do not get out the cores. Remain Blaumeisen sit and nibble diligently pieces from. Titmice and greenfinch go occasionally it, but most prefer to go fishing grains already nibbled so small that they get through the mesh and may disappear with it.
The roof has an inner ring with cut-outs, into which the projections of the ring feeders fit. After having pushed the projections because, one the column simply turns a little, remain so that the projections are located on the inner ring and the roof is fixed.
Thus, the roof can be removed easily in the slopes, because it only holds and the column rotates until it disengages from the roof. Fixing is just as easy.
I do not even look after the cut-outs. I push the feeders ring simply to the inner ring of the roof and turn the column until such time as she slips up into the roof. Then I turn a little further and give them then gently gravity.
It seems a little shaky, but with me there on the column Reger flight operations and so far this closure has never risen. Also, I've never needed much more power and certainly no force to get the roof top or from.
The column is now hanging in nearly two months and unfortunately it rusts at the hole in the roof and the hook that passes there to keep the wire rope. It is our admittedly much raining in between, but if rust on the outside, I expect stainless. Because the price is very low, however, I prefer from only one star.
All in all I am satisfied with this Feeder Very.
