Great tool for someone whose task is to inspect hundreds of hives a day, just the ticket for efficiency. :-D
However, I see no justification for the hobbyist or small time Beek as far as the cost is concerned. I did find the video a little annoying, the part of the "Veteran Beekeeper" unable to start his smoker, the guy by all counts should be an "Expert" in starting his Smoker in an instant. It reminds me of those vacuum infomercials.
