Great concept, bad design.
Great concept however it’s kind of like someone just bought supplies from their local CVS and heat shrunk a bunch of tubes together.  It’s extremely difficult to work with, very inflexible and the trap door closes too slow.  Three times I had fish inside, squeeze the bulb to get the trap door to close but it’s not quick enough.  The fish get out.  I should have stuck with the simpler magnet model.
