This battery / pen / vape / whatever you want to call it, is beautiful. Yeah, it’s expensive, but this compared to what everyone else has in their pocket? This will definitely stand out. It’s sleek, it’s futuristic looking, the charger is great, the auto shut off after 15 minutes is great, and the battery is really good for how often I use my pen. Yeah, it’s expensive, but damn if you don’t turn a few heads whipping this thing out. If you’re trying to decide whether or not to splurge, don’t. Don’t buy this. At all. Stay away. Cause I like being the only person I know with this, and if you buy it, then there’s more of them out in the wild.
