Does anyone else feel like they're wasting their juice in anything but a genesis? Ever since I got my ZAP I haven't even touched my phiniac tanks or vivi novas. The flavors just seem so dull and muted in them and it makes me feel like i'm wasting it. The zap is even prone to leaking but I take it with me everywhere, to work, out and about etc. I've spilled a little juice here and there even then the overall flavor and vapor production is so worth it.
