I bought 3 of them, on initial setup 2 of the 3 kept overheating, no matter the settings or updates etc right out of the box. To e supplier took them back under warranty and did repairs and then sent them back to me. Same damn thing again, I’m trying to get a full refund for thread 2 units now. The other one unit has been running pretty solidly for like 4 mths now non stop with 700-900 /h rate. Not sure why those 2 other units just won’t work but I’m done messing around with them. I’ll keep the one unit running though.
