While I think beekeepers tinkering around have come up with some really neat stuff over the years, I also think some beekeepers have too much time on their hands. Some just want to create something different, slap their name on it, patent it, and smack themselves on the back.
Most new stuff is what I would call a "fad" items, and quickly pass into history. Until some beekeeper years from now runs across an article or a mention of this or that, and the whole process starts over.
While I have bought about everything under the sun when it comes to beekeeping so I could experience the product first hand, I decided to pass on this. ;)
