I have ordered 14 masks on 20th Mar 2021 (Order #4708) and the shipment was supposed to be sent in 3 business as I have paid 45 euros only for shipment. I have sent multiple reminders so far and no re... See more

I have tried several different mask brands and I can honestly say that the Cosmo2 mask is by far the most comfortable and well-made mask I've ever worn. We purchased one of every color for our family... See more

Nice product. Very lightweight. Soft part (face side) is feels very clean and not intrusive. Only small caveat : there should be a metal bridge on the nose to pinch it and make it more protective. D... See more

Finally received the products after 2+ months

Surprisingly after a first review reporting them as scammers, they shipped the masks
They never replied to direct messages.
Masks are ok but 2.5 months is just too long and customer service does not exist
Masks are ok but not worth the waiting time

Very Disappointing Service

I felt I should update my review as I did finally receive my masks 3 months after purchasing them! No contact from Cosmo at all, no apology or explanation just an automated notification saying order was on its way! But they were quick to respond to my review on here! Obviously don’t like people knowing the truth! Even on here they can’t manage an apology. Still would advise touching them with a 10 foot pole!!

Original review: Yeah looks like I’ve fallen for the scam too! Ordered 4 masks for the family on 18 Sep and never got them. In the early days I did receive responses from them but all they did was lie to me and when I insisted on a refund they’ve completely stopped responding to me!! Furious!!

SCAMMERS For sure

SCAMMERS For sure. I placed an order at 17th so Sep, today is 2/11 and still nothing, not replying to emails or even at Instagram messages. I don’t know what else to do. I reckon I just lost 15€ to this scammers.

I have been waiting for almost 50 days…

I have been waiting for almost 50 days for my order. Be careful, its a scam !!! They don't respond to my email anymore. Best move to report them at an official government agency.

Ordered these masks over a month ago

Ordered these masks over a month ago. They take the money immediately then don’t deliver. No masks and no refund. Feel so cross with myself for falling for this scam. How can they do this in such worrying times. Don’t touch then with a barge pole.

Es un robo / it's a scam

Es un robo, hacen el cargo inmediatamente y no envían nada, no contestan los emails y no devuelven el dinero

It's a scam, they charge your card immediately and don't send the masks...don't answer the emails and don't refund the money

Ordered a set of protective masks some…

Ordered a set of protective masks some time ago. They claimed dispatch within 10 days. They not only have not dispatched it but when I contact them they write that it had been dispatched by Deutsche Post and I will get a tracking number within 24 hours. Happened twice in reply to my emails. I keep asking but they keep avoiding giving me a refund. Potential buyers - beware.
