I switched all mine back to 2 piece sliding fronts. Neos 1 piece are nice but they are only up to 36" then they are 2 piece. And the one piece front cages can't be lined up right next to one another or the glass bumps the cage next to it. I got rid of my drop down doors because I didn't like having to open the whole front at once. Some of my spunkier guys seemed to take that as a sign that they should make a run for it. I tried shoe boxes but felt like I had the same problem with them. Half the time they were striking at me as I popped of the top(and then your fingers are real close). I didn't like the system that didn't use tops for safty reasons. The BP and corn snake test run I gave it didn't inspire confidence. A few of them pushed their way out by flexing the box. And the added disadvantage that I didn't feel like I enjoyed the snakes as much when I couldn't see them.
If you are worried about putting your fingers near the edge just open it with your hook
