Hi Christie,
1. Climate and Temperature should not affect how gel works. Gel is dried / cured by UV ray from your UV light.
2. I agree, it is very confused to which gel is the best since there are so many of them.
3. Barb used to make her own gel "Avante" many years ago. Times has changed. She is no longer making it.
4. We carry several different gel system: NSI, LeChat, Star Nail, Elfa....All of them should work, DEPEND on how you want to use it.
Best thing to do: give me a call I can help and walk you through each of these products.
My direct number 847-260-4001.
Best regards,
Kevin Huynh
