Geek info here but maybe some of you will be interested but first: the kid's parents were present, they thought it was absolutely safe to film or wouldn't have let it happen. I was personally there too and having run pistol grip augers for 20 years and the Ergo Auger for 4 years I just know how safe it is; any person (above the age of 18 of course) is in a far safer position than same person running a pistol grip auger because utter lack of fatigue. The design keeps the user strong and able to handle the machine. Also, placement of grip allows for super leverage over the machine. When I say "get some leverage" it's not just a slogan to dupe buyers; if one uses a K-45 and then uses the Ergo Auger in the same application one immediately understands how powerful it is, relative to the old way...money back from Ergo Auger if one doesn't agree. It's the reason why a lot of guys say it'll cut job time in half and make it up to 75% "easier".
