E-cigarette devices and their component parts are continuously evolving. Little is known about the product design features that may increase the appeal of e-cigarette use, ultimately affecting continuation of use. Product reviews have been described as useful in helping to forecast the popularity of products, and online reviews have become an important channel of product information. This study analyzed e-cigarette product reviews to attempt to arrive at a greater understanding of the features of e-cigarette products that may make them appealing to current users.
Data included 248 product reviews found on a popular e-cigarette-related discussion site of Reddit from 10 April 2017 to 12 November 2018. For this study, we examined the sub-sections relating to the positive features (PFs) and negative features (NFs) of the product, found in each review. Common themes were identified and coded.
There were 2929 comments on PFs (average 12 per product), and 1003 on NFs (average 4 per product). Commonly found in the reviews were the ten themes: build quality, color, tip model, battery quality, price, screw quality, power mode performance, coil performance, temperature control performance, and tank quality.
Findings suggest e-cigarette users expect well-made devices and have developed ways to discriminate between products that perform well from those that do not. Findings suggest that the control of price and design features of e-cigarette products (e.g. color, size, voltage, wattage, coils) warrants consideration for future research and policies addressing e-cigarette use.
电子烟设备及其组件在不断发展。对于可能增加电子烟使用吸引力并最终影响持续使用的产品设计特征，我们了解甚少。产品评论被认为有助于预测产品的受欢迎程度，而在线评论已成为产品信息的重要渠道。本研究分析了电子烟产品评论，试图更深入地了解可能使电子烟产品对当前用户具有吸引力的特征。
数据包括2017年4月10日至2018年11月12日在Reddit上一个热门电子烟相关讨论网站上找到的248条产品评论。在本研究中，我们检查了每条评论中与产品正面特征（PFs）和负面特征（NFs）相关的子部分。确定并编码了常见主题。
关于正面特征的评论有2929条（平均每个产品12条），关于负面特征的评论有1003条（平均每个产品4条）。评论中常见的十个主题是：制作质量、颜色、吸嘴型号、电池质量、价格、螺丝质量、功率模式性能、线圈性能、温度控制性能和储液罐质量。
研究结果表明，电子烟用户期望设备制作精良，并且已经形成了区分性能良好和不佳产品的方法。研究结果表明，电子烟产品的价格和设计特征（如颜色、尺寸、电压、功率、线圈）的控制值得未来针对电子烟使用的研究和政策予以考虑。
