*Updating this review* I strongly regret purchasing from this company and wish I'd read the critical reviews more carefully first.I received a Kiierr cap that doesn't fit despite my head being well within their advertised sizing. The product is much smaller than specified and sits awkwardly high. After immediately contacting customer service with requests for a refund and support, I have received no response to any of my attempts at resolution.The cap I received is unbranded and looks nothing like the marketing photos. It appears identical to generic Chinese white-labeled products available on xxxx for a fraction of the price. When I raised this with the company, their response was that "customers prefer" unbranded caps - a claim I find impossible to believe given the premium price point.Examining the review patterns raises serious concerns: most five-star ratings come from accounts with only one review, posted shortly after purchase. There's minimal evidence of long-term use or actual results, and hardly any genuine user photos. Just generic praise about shipping and ordering that tells you nothing about whether the medical device actually works. Meanwhile, negative reviews about fit, sizing, and returns receive no meaningful reply or resolution.Kiierr charges premium prices for a product they refuse to support or service properly.Based on my direct experience, I cannot recommend this company due to their non-responsive customer service and what appears to be a rebranded generic product sold at a significant markup.Also notice the brand new review from a customer who has owned the product for 1 month, who claims it fits his large head.I don't think that that review is a coincidence. Do what you will with that information.
