To calculate the ROI take the 6-10 TH/s from their website (40% spread in the advertised hash rate lol) and throw that plus your cost of electricity in a mining calculator. https://www.nicehash.com/profitability-calculator

nostr:npub17armdveqy42uhuuuwjc5m2dgjkz7t7epgvwpuccqw8jusm8m0g4sn86n3s to add, I don't see the power consumption of the unit on the website. You want to add that to your profitability calculation. However, mining with 6 TH/s or 10 TH/s makes a huge difference. You really want a more accurate hash rate estimate than 6-10 TH/s
