I went to Noir before going on vacation since I didn't want to deal with makeup but still wanted to look good in photos. I got the most dramatic set and WHOA they are AMAZING! They are definitely dramatic but you get used to them after a few days.
The application process went by very fast - the tape isn't uncomfortable and the girl doing it was very thorough. Just make sure not to wear a ponytail or anything in the back of your hair as the couch you lie on doesn't have a ton of cushion and they may start to dig into your head after a bit. The couches aren't uncomfortable though.
I would definitely recommend Noir though - the price is right, and the results are great - they've lasted well now for about 4 weeks. I'm going to schedule an appointment to remove my current ones (I used mascara a few times which prevents them from being able to do a fill) and replacing them with another set - I might go with something a bit less dramatic for day to day office wear.
