Nice table
Sturdiness was not excellent but acceptable for the price. I like the plug and port option making it handy to plug in lamp, phone, etc.

Not happy.
It’s very wobbly. I followed all the instructions but it’s a flimsy and wobbly end table.

Works great for my desk
I like being able to plug things in above and below the desk. Plug in the things below that I want always plugged in and can easily remove the ones on top
