Fraud site, do not purchase.
Fradulent site offering stock that doesn't exist. I bet you're reading this because of that super cheap Steam Deck aren't you?
So, all reviews under the £149.99-£109.99 Steam Deck are stripped from Amazon including the photos.
SumUp is registered to a company in Kent called PTZ Electronics Ltd. They are operating out of a residential address that doesn't match the property owner in public records.
All e-mails come back from Camera Outlet Online UK and not Emmeco.co.uk. Cameraoutletonline.co.uk is currently a badly setup webserver showing it's contents of the main WWW folder (empty).
SSL certificates are provide via LetsEncrypt, a free to use Certificate generator via API. Emmeco.com (the site listed for this review btw) is defunct and showing as no longer secure.
Checking the companies house number results in the company being directed by a Greek Doctor. The company is called Emm Holdings Ltd which doesn't match what Emmeco claim to be. I presume they have chosen this as it matches their name vaguely.
PTZ Electronics Ltd who are taking the transactions have a separate companies house number relating to the residential address noted above.
The site 'Live Chat' is never manned with no one answering questions, it seems to be a way to just send an e-mail to their info@emmeco address that is a alias of help@cameraoutletonline.
Finally, their refund policy is against UK law. Under the distance selling act you are entitled to a full refund when purchasing something online. Emmeco.co.uk claim that 'Sale' items are not refundable which is against this act. The return policy seems to also play towards the 'if we ignore you long enough, the time period passes and we'll refuse to do anything'.
The bank was happy to initiate a full charge back based on the evidence provided to them.
