I know a few who've had them. No problems and they liked them, BUT very $$$, frequent maint (also $$), and very time consuming to apply. Facial cleansing and showering kinda a PITA so as not to compromise the glue (make sure it does not contain formaldehyde). Definitely make sure the person is certified (aesthetician). I might consider it for a beach vacation - maybe - but $350+ & 2+ hours for something that's only going to last 3-4 weeks - doubt it. I use Latisse 2Xweek. Not the same thing, but with Lash Stiletto or Blink mascara, I often get asked if I have extensions.
