Promising review: “Okay, I don’t normally rave about things like this. I bought this on a whim in a last attempt to save my favorite duvet cover. The pills had gotten to the point where it was seriously uncomfortable to sleep with them getting all up in my leg space. I thought I was going to have to get a new duvet cover entirely. Along came this lil’ baby. Not only is my duvet cover basically brand new, but I have found a new hobby. I’m depilling everything. Sweatshirts, leggings, blankets, socks, anything that looks like it needs some love. It does the job quickly and leaves everything looking fresh. Hi, I’m obsessed. I can’t stop. I should send this back. I’ve started asking if my neighbors need anything depilled. I’m going to buy one of these for everyone in my life. Everyone needs to own this. Take it away from me.” —Sydney Jensen
