Cool.
I suppose one might make something similar from household items. But not just any plastic tube would do. These tubes are coated in the inside to allow the crickets to gain traction, so that the tubes readily fill up with crickets. One just has to remove a tube and shake it at feeding time. Nice idea. I used to just keep my crickets in newspaper. Paper towel rolls would probably do just fine if they're occasionally changed. But don't you have crickets hopping all over the paper towels when you go to remove them? Not that it'd be a major problem to just shake them off, but there'd be escapes if the shaking is not done carefully or in a deep enough container. Not so with these, as the outside surface is too smooth and inclined for the crickets to climb up. Also, with a roll placed horizontally, I'd think there'd be dead crickets among the live ones if its not set at an angle. With these tubes, however, I suppose the dead ones just fall down to the bottom of the tank.
As far as it being in the testimonial section, well it could even go under Product Reviews for that matter. I was thinking this might stimulate some discussion on the best way to keep crickets -- seeing as the description for this general topic is discussion of "the culture of live food, feeding techniques, and any thing else live food-related." Perhaps I'll alter the thread title to something more general
