Like this feeder a lot!  It is solid and quite heavy, so it won't whip around in the wind.  The material is water repellent and does not look like it will fade too much.  The design is great, the top just lifts and is held in place by its weight, which means you can open/close it with just one hand.
The dimensions are just for one standard block of suet. There is enough of a perch for birds but squirrels might find it hard to hang on (though I personally do not mind squirrels eating from the feeders, everyone is welcome).
So, this is a really high quality and well made feeder which looks like it will last for years and years to come.  Very happy with it!
