I used the cheap store brand stuff for years...until I found Zoya. It works like a dream, even on tough glitter polishes. I tried what it suggested and swiped some on my nails before painting them, and my manicure lasted TWICE as long. Finally, the smell is mild and doesn't give anyone in my home headaches. The pump dispenser is super easy to use. The only downside is that it's leaked both times in the mail, but Birchbox was awesome about replacing it. Recommended!
