Won a five pack of both the L400 and L500s. Tried one of the L400...elements of bitter, almost sour taste, had to relight halfway through..wholly unimpressive..I attribute that to needing some time in the box...the other thing I noted was that a number of them had pits, and, in one instance, a crater of missing tobac in the foot...has anyone else noted qual control issues with the ligero?
