I was a happy Technobit user, I know they get shit around here for missed orders but always worked for me. I got out of the mining game early 2014 so not very current.
I was thinking about picking 2 of these up to throw in to a solo pool for a lottery try a few months ago as the price dropped to 70 Euros; in my view worth the risk to sit in a dark corner and just hash on the off chance of hitting gold.
However I have sent 3 emails to Martin/Techno bit, no response, they have removed the paypal option on the website while leaving back transfer bitcoin payments (non reserve able) which does concern me.
All in all, hold off, I think technobit are gone :/
