Review (3/5): Good if you're on a budget,  work well
These are light weight and magnetic, which means they're removable from the stand. I do think they feel somewhat fragile, but there have been no breaks yet! A couple of the tiny magnets did pop out, but I stuck them back on with clear gel polish - worked in a pinch.
I wish the bases were heavier and that the magnets were stronger for more stability, but they've worked well enough. I've done 4 sets of nails using these and will continue until they break.
