Heat It fits on a keychain, and plugs into a smartphone on one end. Users apply the other end to the bite, and can control treatment temperature and duration—with options based on a [peer-reviewed study](https://medicaljournalssweden.se/actadv/article/view/11592/19095 "undefined") of more than 12,000 insect bites—through the app. Heat It recently launched at U.S. REI stores and, per Liedtke, has sold around 1.6 million devices. **Buy Now:** Heat It on [Amazon](https://amzn.to/4odCZs5 "undefined") These are independent reviews of the products mentioned, but TIME receives a commission when purchases are made through affiliate links at no additional cost to the purchaser.
