CNN Underscored continually testsproducts—whether it’s a dash cam, flosser, or gaming monitor—to find the absolute best in every category. Our testing process is rigorous, starting with hours of research to find the top products in each category. Once we create a product testing pool, we test and retest each product multiple times in a live environment over weeks or even months.
This year, we’ve tested dozens of products—from bidets to mesh Wi-Fi routers to fitness earbuds—to find the best products you need to make life better. Below are the winning products for October.
