Hi,
I had one when we move to a different state and my furniture was going to arrive 3 days later so we needed a place to put our 1 year old to sleep.
I have the blue and red one, I don't know if the difference is just the color.
I like mine but it wasn't amazing, she wouldn't want to go there and sleep, so I would have to wait for her to sleep and then put her there. She would roll to much to a corner and get in a gap between the inflatable "mattress" and the tent. But she always have move A LOT while she sleeps and even turn on her own crib, so I can understand that. I fix that problem by putting her sweater in that corner.
I thought about re-sell it but even if it is not as amazing as I wish, still do the job, is very light, easy to carry around and she now plays with it sometimes as a play tent and it has hold very well.
If you don't mind to co-sleep with your baby then you should bring this back, I am not sure it will really fit a 3 year old comfortable. But if you are looking for a travel bed this does the job and you can even a sun shade for the beach, you could keep it and use it later as a play tent.
