It obviously wobbles a bit on the bed since a bed isn't a hard flat surface, but on the ground, it's extremely sturdy.

I am very happy with it. Does homework and colors. People complaining saying the cord is too short. I use it while sitting in a recliner to use my laptop. Even so, it's definitely worth it, and I'd happily purchase it again if so needed.

I have a bar stool, and sometimes I put the table on top of it, and it works as an end table.

While I won't allow open-cup drinks on it in bed, I'm not concerned about spills.

The advertised video shows the person using a portable power bank, the ones you can charge your phones and laptops with, etc.
