I've tried so many waxing products, but I always come back to this. I don't actually use it on my bikini line, so I can't speak to its effectiveness there, but because of its sensitive formula I really like this for my upper lip. I've been coming back to Gigi's Microwave Brazilian Wax for YEARS, and it's always so reliable, so effective, and so quick and easy to use (and no annoying strips to deal with). No weird scents, no irritation, and you can often find it in a nice kit that has everything you need for a waxing experience. I've been using this since I was a teenager, and it's still my favorite wax.
