It's slightly challenging to hit the sweet spot but nothing to complain about.

It does take a little practice to get it in just the right spot for it to

However, the one I got with loose magnets was almost impossible to suspend in the sweet spot, and it quickly fell to the base

But sometimes it takes me over 30 minutes to get it in exactly the right spot to get it to float.

You literally need to find that ONE perfect spot for the magnets to repel each other and hold it up in place

The power button is a tiny physical button that is nearly invisible, and trying to push it prety much requires you to remove the orb, turn it on, and then go through the hassle of getting it back into the megnetic sweet spot.

Just use both hands, one on either side, and you'll quickly find the sweet spot

2. cup your fingers under the orb (more supporting than holding but at the same time preventing it from flying to the magnetic base) and pass over the base very slowly and at first in a circular motion so that you can feel the magnetic pull increase/decrease and when you hit the sweet spot the orb pulls upward ever so slightly and floats a couple centimeters above the base

Getting the orb into the magnetic sweet spot is a bit tricky, but not so bad once you get the hang of it.

The one with good magnets in the base is relatively easy to position so that it is suspended, and it doesn't have any issues wobbling out of the sweet spot and crashing into the base

Took a minute to find the sweet spot for levitation, other than that easy to setup easy to use.

Great cool factor, but a real challenge to find the sweet spot to get it to float.
