I love the showmanship of these kinds of booth, when salesmen are ready to present on their product and why you should buy it. I still laugh at the booth that tried to shoo you away, because these videos reach a market that they just don't have access to advertising-wise.
I highly recommend the G-Gun from Lock and Lube. Iv'e had it for a few years now and it makes greasing my excavator and loader a pleasure. I think that the salesman meant to say that it holds 2 gallons of grease which is far more than 2 pounds. I buy 35 lb bucket of red tacky grease.
H Stanley, trade shows are not usually my favorite videos, but I did like the pull-out toolbox at the beginning of the video. I am thinking with a pull out could you get more stuff in the toolbox? Just a thought for now.
