I ordered the starter kit in the hope that the nail polish longer remains on your fingers and you do not need to repaint every 2 days. The LED lamp is commercially available and with 2 timers installed 90/120 sec. I can not say anything negative. However, the gel is a einzie disaster. The Dual Coat is still reasonably well distributed, but the nail polish is so thick and hard to apply, that the nails look thick catastrophic thereafter. One and only Advantage is that the whole is easy to remove. 1 x briefly linked arms with the Rose sticks and nail polish is from.
Conclusion: Good idea, bad implementation because paint too thick and brush of poor quality!
