I've had the Nulids device for just over a month. It's hard to tell if it's made a difference. I have dry eyes as a result of eyelid surgery so I don't know if this will resolve my issue but I'm trying everything. I would return it to get the 30 day refund but I've heard sometimes it takes six weeks so I guess I'll keep trying. I may need to get IPL first. I'm sorry that you have to keep buying tips and the lube every month.
