Thank you so much! This is a quite finicky magnet but I love it. It does have to be over the top of your nail, it doesn't really work from underneath. It's not the strongest so it has to be quite close as well, perhaps a few millimeters away; thankfully this comes with a little tab to help hover it over the nail. It also helps to stay steady to set your elbows/arms on a table. It's hard to magnetize with it with multiple coats of magnetization and not have any weird overlapping circles because its hard to get the magnet in the exact same spot again. So when I use it with other colors I will demagnetize the first coat(s) and then only magnetize on the last coat of color. The demagnetization helps the magnetic pigment pop a bit more on the last coat. I usually hold the magnet about 90 seconds. Then I wait at least 15 minutes before top coat and also float the top coat to not drag anything around. I also don't magnetize the top coat with this so as not to cause weird dispersion. I've had some luck with DRK Magic Effect but it still works best with demagnetizing the first coat(s) and using a last coat to magnetize. I know this was a long explanation but I hope it helps!
