I have purchased from them, they are legit. And actually accept paypal which is unheard of and truly helped me decide to go with them over others (buyer security).
To be completely honest, they fantastic and customer service is better than expected. I got a Dayun Z1 pro and one board kept failing (possibly user error as they seemed to get it working...) but Gavin (legend) agreed to let me switch for 2x Innosilicon T2Tz.
They Ship from China as expected so you'll get import fees but their prices are fair. If you are in the UK, use a forwarded to get cheaper prices as they charge for the UK tax, dunno how that works but you'll save like 10% sending through Germany or whatever.
I plan to get a couple more and would feel completely safe using BTC / bank transfer now, given my experience with a paypal transaction.
No offence but Providing some proof of how friendly the customer services was and how they helped you would be much better.
Not so many people will believe what you are saying from just words... me inclusive.
Not a problem, happy to help with your confidence in these guys because its so f*cking hard to find ASIC sellers that are not scammers. Coin mining central are decent guys are you can definitely trust them
So, here is my transaction with them and some snippets of the convo I had to get a replacement. The replacement cost more so I did pay extra for them.
