Ordered a product 17 days ago Ordered a product 17 days ago, put in an inquiry at the 2 week mark as to its whereabouts and still no updates. For a product thats advertised to arrive in 5 days. no updates/ apologies, its not really what you would expect. Feels more like a scam.

Their product didn't work Their product didn't work. Customer service offered a partial refund (excluding shipping costs). That's unheard of. When a product is returned, all payments are refunded and some will even send the client a free shipping label. When a product is faulty, that's goes without saying.

Absolute disaster Absolute disaster. Stay away. No customer service. Yubikey does not work well with Google Chrome and windows 10. I was locked out of all three of my crypto trading accounts after the first day with an error message on all three that said my device was not recognized by windows Chrome security and to try another key.

UK customers - Beware the artificially high shipping fee I placed an order with Yubico. They charged EUR15 for shipping. My order was delivered by Royal Mail Tracked 24 service. According to the Royal Mail website, this cost Yubico GBP3.30 for an 80g shipment weight as declared on the Royal Mail label. This means Yubico have charged an artificially inflated price for shipping (GBP3.30 is EUR3.75, which is substancially less than EUR15)

Using Yubikey introduces the risk of the rightful owner of account is prevented access. It is a problem that Yubikeys cannot be duplicated for backup. They are so secure that even the owner of an account can be locked out, lol. That's not good. In case of lost key or hardware malfunction there is no way to access your account. Unfortunatly two different keys often cannot be registered for the same access. Using Yubikey introduces the risk of the rightful owner of account is prevented access.
