Actually it hasn't. The tire's original tube (from when I bought the bike) was the one whose valve got snapped by the hand pump. The other two tubes were Kenda tubes installed by the bike shoppe. Both of those tubes went completely flat while the bike was sitting and the second one while the tire wasn't even on the bike! The other two tires retain their original tubes from when I bought the bike and haven't needed replacing yet. I assume that that brand of tube is good but I don't know what brand they are. WalMart assembled the bike for me when I bought it so I never saw them.
