CharmCaster? Glass Bead Pro? Others? Help!

I'm brand new to magnetic polishes, and I have fallen so hard in love. I did a manicure with unmagnetized EdM Sunset Over the Bay. So gorgeous! But that was a super-fast slippery slope to magnet acquisition and experimentation, which I'm enjoying.

So now I want a gizmo to help me get other effects. I've seen some lovely glass bead manis, and I did try to get a Glass Bead Pro during their last recent drop, but didn't make it, alas. Now, just a few minutes ago, I saw a CharmCaster mani posted on this sub and loved the look of that. Very different than the glass bead, and just as striking to me.

I have zero experience with these devices, and not much yet with ring and bar magnets, but I love the effects. Those of you who have the CharmCaster or Glass Bead Pro (and those who don't have either yet but are determined to correct that), do you have any advice or comments about why you chose that device? Have you been happy with it? Are there any other magnetic polish devices I don't know about that you recommend?

I'm feeling obsessed yet under-informed. Laqueristas, help me spend my money! 😂
