I have bought several brands and this is by far the best at a decent price point. They provide everything needed except the lamp itself. Easy to install and looks just as good as if you gone to the salon. I like that these are thicker than most because I have flimsy nails and all polish never lasts for more than a day before chipping. I had these on a week before starting to chip. And I work in Healthcare so I wear gloves and washy hands constantly. No need for base or top coat. And I love the colors, only con is I wish there was more options to choose from. (Def don't usually leave reviews and I don't get paid for this review but this product deserves the great review)
