I bought one at our spring meeting & really like it. It is plastic (in a wooden super) with a snap top lid. The bees come up through a circle that has a cap on it. You can take the lid off and see them feeding. So far, this is the only feeder my bees are using. Possibly because it is on the strongest hive. The only thing is, there is a small gap between the super and feeder. So far no problems with it, but if it was fall, might set off robbing. To see, it is on page 67 of this year's catalog. Cat#12-S.
