Hi Cadzyy,
Welcome to the forum! You can order either French lace of Super Fine Swiss lace. Attached properly both are undetectable. The French lace is slightly stronger but both are excellent. Under typical conditions users usually get about 4-6 months out of a unit. Some get over a year but that's not the norm. They 'baby' their units and get more miles out of them. What's better---glue or tape? That's a personal choice up to the user. It depends on how often you want to take your unit off, your lifestyle and 'what works best for you' I use a combination of both. I attach with Walker No Shine tape and for touch up I use either Base Bond or I Glue. You'll just have to experiment and see what you like---it's 'trial and error.'
Regards,
John
