What Shoppers Say About FLEX
Created with AI, based on recent reviews
FLEX shoppers are deeply divided in their experiences. Half of reviewers give five-star ratings, praising the product quality and effectiveness, with particular enthusiasm from customers who have switched from competing brands and found the removal and cleaning process significantly easier. Multiple reviewers highlight responsive customer service and appreciate the company's sustainability focus. However, the other half express serious frustrations: two one-star reviews cite major shipping delays (nearly two months instead of the advertised seven to ten days) and unclear subscription pricing that doubled after the first order without transparent disclosure. A two-star review notes that international customers may face unexpected shipping costs and poor logistics support.
The core product itself receives consistent positive feedback regarding comfort, functionality, and ease of use. The primary complaints center on operational issues: delivery times that don't match advertised timelines, subscription terms that are not clearly explained at signup, difficulty canceling subscriptions, and international shipping logistics. While customer service responsiveness is mentioned positively by some, it appears inconsistent in resolving complex issues like missing packages.

My order took almost two months to arrive, which was really disappointing. When I reached out to customer service they said they'd run out after the first month and shipment would happen soon. Two months later the package finally showed up, even though their website advertises seven to ten day delivery. I was genuinely pumped about this product before all the waiting.

Initially loved it because the products work great and feel amazing. Things went downhill when I realized my subscription price only covered the first shipment, then it doubled for every order after that, which definitely wasn't spelled out when I signed up. Fast forward a few months and I got pregnant, so I needed to stop everything. I tried canceling through their website and thought I'd taken care of it, but then two more shipments showed up anyway. Couldn't find any way to cancel online, so I emailed asking them to shut down all my subscriptions since I wouldn't need the items anymore. They said they'd handle it and I got three emails confirming cancellations. Now months later I get a message asking me to update my payment info for an upcoming shipment. I never resubscribed to anything. This company keeps trying to charge me no matter what I do. Don't share your card details with them if you value being able to actually cancel.

Great product and shipping to the UK was super fast. Really happy with this purchase.

Flex completely transformed my period experience. I'd tried the Diva Cup, Saalt Cup, and June Cup before this and they were all disappointing in different ways. Every single one leaked, was a pain to clean, felt uncomfortable, and taking it out was honestly awful. With Flex, removal is simple and zero mess. Plus it's comfy, super easy to clean, and made me wonder why other companies haven't figured this out yet. Here's something else I love about them: they actually include a full guide in the box with instructions on insertion, removal, and tons of helpful tips all written by women. If you're thinking about trying a menstrual cup for the first time, this is genuinely the brand to start with. Nothing else comes close to how good this one is.

Amazing customer service and the product itself is solid. I definitely think this company has a bright future ahead. I started with a recurring disc subscription, then switched over to their reusable cups instead since they're way better for the planet. Getting into my account to cancel the disc subscription was pretty frustrating, but I shot them an email and got a response the same day. They hooked me up with instructions to fix my account and went ahead and cancelled my subscription without any fuss.

Heads up if you're ordering from outside the UK: they run a UK website but actually ship from the US, and yeah, you get charged for that international shipping. I get that ordering internationally happens, but claiming a UK address is misleading. Their shipping partner has been a nightmare too. My order disappeared one time and customer service across multiple departments denied me a refund. Only after my bank stepped in did they finally give me my money back. Over six months I gave them a real shot, but every single delivery turned into a headache. Plus I'm skeptical about their green claims when everything's coming from America anyway.

Grabbed some flex discs and they're honestly great. Really comfortable to wear, you hardly notice them at all. The only real downside is they're not reusable. If they made a reusable version it would be so much better for the environment.

This brand is seriously revolutionizing things for us women. I've been using their stuff for several months now and honestly can't imagine going back to tampons. Two things would take it to the next level: making the packaging greener and adding some kind of giving-back program. Since they're still fairly new, I'm pretty confident they'll move in that direction as they grow and do well.
