I had them while being on a summervaction (swimming a lot). I wanted to have them so I could feel comfortable without wearinga ny makeup at all, only the lashes. It was worth it for the summervacation but I would not do it again since it irritated me that I could not sleep normally: when laying with your face on the pillow you will misshape them, so you have to sleep on your back, or hope you dont sqeeze them in weird positions. Also I didnt liked it that I had to be so careful with it- while cleaning your face or rmeoving other makeup.
They stayed great for 2 week, after that it went downhill- loosing some lashes and getting them beaten up by laying on them while sleeping. After 3 weeks I got them removed which by the way hurts like HELL. Like having acid in your eye- would have liked a warning for that.
So I will stay using fake lashes instead- they stay beautifull for a long time (i use them quite often for 1 month or more) and they only cost 7,99 and dont hurt or irritate
