IIRC I sent one of my free roses to my current girlfriend. She wasn't one of my standouts but I wanted to get her attention and it worked. With how many normal likes she showed me she had in her inbox, there's no way we would have even chatted if I hadn't jumped the queue.

The "Standouts" feature still felt like a total scam to me though. "Here's a bunch of women we think are out of your league, pay us and we'll let them know you exist".
