I am sadly unhappy with this! It does NOT do a good cure, especially compared to the standard usual big plug-in Gelous lamp. This one baaarely cures the top, and doesn't do anything to the sides/curves of the nails! I was left with goopy sides that wasn't cured and I had to hold my nails to the side and pressed right to the LEDs, and ended up with an uneven, ugly, weird cure, which was SO tricky to file and redo when travelling, which I was. Very disappointed. I also used all Gelous polishes, so it should've worked perfectly.
