Evkoo

I ordered an iStick with these and within 24 hours I asked to cancel my order (no cancel option on site, you have to email them).
I received a reply that was reassuring so I decided to give them a chance. Within 24 hours they posted on their website that there would be delays so again I asked to cancel and not to ask why, just cancel.

Anyway I finally got refunded after a couple of weeks.

I get the impression these guys are genuine and you will receive what you order, it's just the shady way they go about their business.
I think they just do group buys but they don't tell you its a group buy so if you order first you could be waiting weeks for your device which certainly seemed to be the case with the iStick, many people hadn't received a tracking number 3 weeks after ordering.

One of their representatives on FB, when asked who manufactured their Hana clone, stated it was in fact an authentic lol.

I notice now the are selling this and it's in stock (!).

No info on it whatsoever and not even any pictures, only renders. No doubt this is another pre-order/group buy but this time it is for their own device and you buy off plan, they just don't tell you that.

BUYER BEWARE!
