I ordered this over a month ago (4th Apr 2023), it has still not been delivered and I have received no reply to the three emails I've sent.

After ordering, I initially received an email saying that they were low on stock but can be replaced by the regular mask and an upgrade kit. I accepted this (5th April) but haven't heard from them since. I wrote two further emails asking for an update and then for the original product but received no reply. I wrote an email to the support department and haven't had any reply from that either.

unfortunately, it does not fit well around my mediterranean nose, so no matter how i wear it, i will feel the air hit my eyes once i exhale. i tried a nose clip, does not work. i should have checked this before buying. im sure it fits well for people with "normal" noses.

however, there is no excuse for the way swiss post handled my package. they left it under the doormat. nobody does that around here, nobody. i live in the city. please tell swiss post i will never use their service again.

otherwise, great product, all of the other area's fit well and i like the minimalist filters. would buy one that fits my nose, but not if delivered by swiss post.

The mask is fine but left a strong chemical taste in my mouth.

The mask is too shallow for my face. I can’t wear it and will try to find someone to give it away to.

I wrote about returning my masks (or at least the unopened box of filters) a week ago and have not received a response. The mask wasn't for me and I would love to recoup some of the money.
