Excellent, easy fill feeder. I have had the feeder on for 3 weeks now and no drown bees for me. Other people said they have had drown bees. If you use it with the clear center cup/piece like intended there is no way for them to get into the big pool of food. If you do get dead bees inside the center cup/piece (I have not) it would be from the bees killing each other.
It's not drown proof. But it fits into my eight frame deep and gets the job done.
Great addition to the hive.wha a timesaver.
I have always used entrance feeders in the past, but I could not do that with my new Warré hive. I found this one online and was very pleased with it. The bees were able to access the feeder easily, but were not able to get up into the top box. Next year I think I will buy another one for my Langstroth hive.
love the feeder, it really helped my bees get off to a great start. thank you.
