Charging for Quattro?

[Lemmonie]

Hi everyone.

I have just purchased the Star Nails quattro clear and white tip to provide a permament French for my clients.
A few questions please if you are able.....

How have other technicians found the product?
How do i charge for it?
Does it compare with the Brisa brush on gels?
Will it add any strength (however minimal)?


Thanks in advance!
