The first question is simple: what are your customers looking for? Some want a disposable that lasts a week or more without recharging, while others prefer to switch flavors every day. If you're not sure, look at your sales data. Do you sell more high-puff devices, or do customers gravitate toward smaller, more affordable options?

For heavy users, a high-puff device like the VERTEX-25K makes sense. It's built to last, which means fewer returns and more satisfied customers. For lighter users or those on a budget, a smaller device like the LINQ-SLIM keeps the cost low without sacrificing quality.
