I have a lyson hive and thought this would do the trick. I'm not quite happy that they leave a space between the top edge of the deep and the cover as the ridge around the edges stops the outer cover from sealing against the lower deep . I suppose that will be ok for the short amount of time to feed.
Also there is no apparent way to remove the ladder to clean under the ladder ( without breaking ) or to rough up the inside plastic. Bees are going to drown . They still do with my other top box feeders.
I think I can use with my wooden ware hives but I will know more when I deploy them this weekend.

Great product without having to also buy a wooden box when it is not needed. Thanks Perfect Bee!
