Antminer S21+ Reliability | High Failure Rates Continue to Shock Owners
A wave of complaints from miners is raising alarms about the reliability of Antminer S21+ units, with around 70% reportedly needing repairs. Users are growing frustrated with revenue losses, igniting debates about the machine's operational performance and raising questions over Bitmain's response.
Reports on Failures Intensify
Comments in various forums reveal a distressing situation. One miner running 10 units said, "Around 70% of the units have been sent back to Bitmain for repairs." This clearly flags concerns about the product's durability.
Interestingly, comparisons are on the rise between the S21+ and alternatives like the S21 Pro and L9s, which reportedly experience no downtime. One owner pointed out, "I am also running S21 Pros without any downtime at all," underscoring a growing demand for more reliable options.
Concerns About Hosting and Uptime
Financially, many face dire situations. "Repairs under warranty are reassuring, but I'm losing out on mining revenue," stated another miner, stressing the stakes involved in this competitive environment. Community discussions highlight worries about hosting conditions, suggesting they may not effectively mitigate environmental factors like humidity and dust – potential culprits in premature unit failures.
Doubts About the Warranty Process
A troubling sentiment is emerging as more miners report issues with Bitmain’s warranty service. One miner shared, "I had a S21 Pro die after 2 months. Three months later, they deemed it 'unrepairable' and I was out 4k value of the unit." This has led users to doubt the manufacturer’s commitment to customer service and reliability.
One contributor noted, "Hosting facilities will never take blame for damaging units," highlighting the tension miners feel regarding repair responsibilities.
Community Sentiment and Alternatives
Voices from the community indicate a serious shift in attitudes—"We have been turning all of our clients away from the S21+. It’s a very sensitive and poorly made miner," echoed a comment that reflects growing discontent with the S21+.
"Same issues as S19K, honestly. We typically recommend better-built miners than Bitmain's units."
As miners express dissatisfaction with the performance of S21+, the need for transparency from Bitmain grows. With mounting pressure, will they offer solutions that restore faith among mining operators, or are users poised to abandon ship in search of more dependable hardware?
