Swift delivery and quality product

The delivery was prompt. The cap appears to be of high quality, fits well, and the 6-minute sessions are manageable. I've noticed improvements in the first month.

Quick and user-friendly

Using the cap is straightforward with 6-minute daily sessions that seamlessly fit into my routine. The cap is comfortable, well-constructed, and feels like a premium device backed by reliable technology.

Smooth experience and quality device

I just received my laser cap, and my experience with the company has been very positive thus far. Ordering was easy, shipping was prompt, and the packaging felt top-notch. The cap is comfortable and well-made. The company excels in clear communication, product education, and strong warranty support. Everything from setup to instructions was clear and professional. I'm eager to start using the cap regularly and see results.

Prompt delivery and easy setup

My laser cap arrived ahead of schedule, which was a great start. I've used it a few times since receiving it. Setup was simple: charge the battery, plug it in, and press start. It beeps every 10 minutes until it reaches 30 minutes, then turns off automatically. I appreciate the recommendation of using it every other day instead of daily. The device fits well, targeting all my thinning areas. While the design may look amusing, it seems durable and provides a warm, relaxing experience. I haven't seen growth yet, but I'm hopeful.

Trustpilot encourages honest customer…

*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.

Company takes money and don’t deliver

I bought the laser hat in the 1st of Dec 2025. Reading reviews here I also was tricked by their 2 day postage service. They do have fine print due to busy take 10 days. We are way past that now. Not a fan of fine print tricks by companies. Now I have reached out and no replies. They are happy to keep sending spam emails to buy more stuff. In Australian dollars this has cost me over $2k. That’s not small money. You expect replies to emails, updates on postage or delays. Giving it one more day and will go through PayPal get my money back and buy the irestore hat like I should have. Stay away from this company Update: they did finally reach out say would cancel order. Then silence again. No answer as to when. Or how being paid. I just got money back through PayPal.

The item arrived in pristine condition but as it arrived from USA, I had to go out and get a USA to UK adapter.I charged up the battery and used it for the first time, for 6mins, all good and very high quality product.

Happy so far

I just bought this last week and am very happy with the customer service and the quality of the product. Over time will see the results, they do offer cash rebates for leaving reviews so worth keeping that in mind when reading all these.
