Any feedback on StrongU STU-U1++ miner anybody?

Hello forum friends!
This miner is showing an incredible profitability, so my question is what’s the catch? Anyone here has any experience mining with it? Price seems to be reasonable too - am I missing something?

Try and get hold of one, I did and couldn’t!

You can grab a Stu1+ 12.8 Th/s on for about $5700 plus shipping. ROI puts you about 6-7 months and I believe he offers a 30 day warranty which most used guys don’t!! He really checks these things out before shipping. Good guy but it’ll take about a month to get. Good used miner supplier IMO. Good luck either way. I’m not affiliated in any way, I just like sharing info about people in the biz that don’t try to scam you!
