I lugged my portable playpen around for my babies to sleep in many, many times. Yes, my kids also needed darkness to go to sleep, but if I had been in a strange place and tried to put my baby down in the playpen and then put the prison on top, completely blocking their view of everything around them, they would have completely lost their shit the same way the "model baby" did. There is no way this would have ended well for me, so I'm somewhat shocked at their sales. Maybe this works for a 3-4 year old toddler that you can reason with and turn the prison into a fun hiding-fort-sleeping-game to some extent, but for a 1-3 year old, no dice.
Fortress needs to figure out a way to market that cool looking layer with a thin windbreaker fabric on top, and then he could kill it on the market.
My screens are in a frame and I just have to push down on the right, then the left and they pop right out. They are in good shape. These other screens are very cool, but I'm not sure why people would need replacements too often and I don't have any problem taking out my existing ones. Maybe I'm missing something.
I have no idea what the Zuum boys were trying to get money for. Their product was cool but they had zero business plan.
