I love Gellae- i will always recommend this brand to everyone because of the variety of set designs and they work. I have previously used competitors to see any difference in quality etc and there is.
Gellae will last me 2 weeks before lifting up (i won't have one set on for more than 2 weeks because I get bored so i will change sets) - but competitors i have used last top 4 days before they rip, chip and lift up.
