My hdb,s are fine the only Issues Lackland say they have had are people expecting the battery to work in extreme frozen temp like being left out side or on the truck deck.I would take the warranty that Leica (lack lands)offer all day every day over the swaro's.Correct me if I am wrong doesn't the swaro warranty period last 12 or 24 months?even if the leicas are slightly behind in glass still more than happy with mine.
