Interesting to see your thoughts!
Tom Back is my nephew and I have the original thrive hive in my garden. I am as sceptical as many of you, but am hoping to put a swarm into it very soon to give it a try. I have already made one change, in that I have removed the straw from the roof and replaced with an oversized piece of plastic to make it a little more suitable for our weather!
The top bars are tight so in theory the bees cannot access the area between the top bars and the roof, so the roof should not get propolised as someone suggested (I say SHOULD NOT!!!!) but I totally agree about the lid possibly falling shut being a problem. The hive is currently situated in a very sheltered spot so I hope it will not get too wet or battered.
I look forward to being able to report really positive things about this hive!
