It is very easy to fill (just depend on lid, feed pure, lid on, hang) and very easy to clean thanks to the simple, complete disassembly of the items. The funnel shape of the lining falls to reliably and can not get wet because of the overhanging roof (at least for me, since it depends namely in the tree.) The shell is so high that the food can not be simply herausgescharrt.
However, it falls to the birds difficult, to fly to the cottage at no extra approach rods because the bottom shell is very close to the hopper. I managed this situation by I drilled 4 tiny holes in the shell, 4 pens thick bamboo poles had tied of approximately 24 cm length with a thin wire under the edge of the feed bowl and the individual bars at the ends also connected to stabilize with wire.
The first great tit had found the new feeding site within half an hour ;-)
