I have the cignot coffee and capp flavors in VG. The flavors are good, but there's not a whole lot of it. The coffee is more noticeable, so I use it as my all day vape. I do have some Cafe Mocha coming in from tastyvapor right now, so I'll report back and let ya know how it is.
P.S. - While cignot's coffee flavors aren't what I expected, the Ecopure English Toffee they sell, as well as the service, is AWESOME!
