I was worried about overheating, but the S21 Hyd. has been running cool and quiet. The setup was a bit more involved than other miners, but it was worth it for the peace of mind. The performance has been excellent, and I'm very happy with my purchase.

The KS3 is a beast. It's been running 24/7 since I got it, and I haven't had a single issue. The hash rate is consistently high, and I've seen a significant increase in my earnings. It's a bit loud, but that's a minor inconvenience for the performance it delivers.

I snagged the T21 during a sale, and it was an absolute steal. It's been running smoothly, and I've been happy with its performance. It's not the most powerful miner, but it's definitely a great value for the price.
