When it comes to life-changing products, there’s a very fine line between “weird” and “genius.” After all, if an item was typical, you’d probably own it already. These odd but brilliant Amazon products are selling out for a reason. They boost your efficiency, brighten your day, and improve your home in ways that you might not expect — and if you’re hesitant to click the “add to cart” button, most of them are backed up by hundreds (if not thousands) of rave reviews.
