If it works, that's all that matters. I usually make the bottom a little deeper, so the crickets have a harder time jumping out. I make it tall enough, so they can't grab the front edge with their front legs to climb out. If they're staying there long enough to be eaten, it's good.
My pictures come out sideways for some reason, it is up right stuck to the side side of the viv with suckers. It is working quite well crickets can't seen to escape.
looks good.i was thinking of making one of these but sully wont eat from a cup.
just make sure all your crickets arent over dusted tho as the ones in the pic look like ghosts
