IMO, Madvapes TopVapor line is cheap, but it is not OK. Do yourself a favor and try something else, really anything else.
There isn't a really good tobacco flavor at rock bottom prices. For really good tobacco flavors at mid-range prices, try Backwoods Brew (Casablanca, Backo, Virginia), Nite Lite Vapor (Gold, Twilite, Bounty Hunter, Harbor Nite) or upStomp's White Spur.
