This sub in general is very skeptical of online influencer brands like the ones you mention, who spend enormous amounts on marketing with often middling actual product quality. And yes, they absolutely pay out tons in commissions to reviewers and social media influencers to feature and “review” their products. I’m not saying everything they sell is bad, but many of their products are certainly lower quality than older, less internet savvy heritage brands and even just normal department store brands. The money for all that marketing has to come from somewhere! My Brooklinen sheets lasted about 2 years before completely falling apart; that should not happen with a $200 sheet set. If you are in the market for a down duvet insert I HIGHLY recommend you buy it on eBay. There is a ton of department store overstock and you can easily get a super nice insert for substantially less than you’d pay at retail. I recently bought my mom a new medium-weight queen down duvet of the Bloomingdale’s store brand, I paid $56 plus shipping for a duvet that retails for like $500. That was a pretty good snag but not as rare as you might think. The only downside of going this route is most of the overstock vendors do not allow returns, so do your research on dimensions, down fill power, fill weight, and so on before buying anything More on reddit.com
