I invested $50k in 4 S19 Pro 100TH… I invested $50k in 4 S19 Pro 100TH miners since 2022. It took 6 months for them to start running after the initial investment. However, they only ran for a few days before shutting down. Correspondence via email took up a lot of time. Overall, the running time of the miners was significantly less than the downtime. So far, I've earned about $7k, not including increasing hosting fees and occasional repair costs. It's exhausting. I'd rather have spent $50k buying Bitcoin; I might have made a profit. The company lacks credibility. I trusted what they said initially, so I boldly placed my money in their hands, hoping for mutual benefit, but I was wrong. I lost sleep worrying about it. I still paid the hosting fees promptly when they sent me a bill, but they kept making promises month after month while my machines were not operational.

Good and accurate support and help Lea at Compass Mining had helped me with a question about placing the newly purchased miners on a different mining pool and I was very happy with the quick headsup and accurate information given to me by Lea !!! Everyone at Compass mining starting from John Degnan in Sales to all of the Support Team get a 5 Star ***** Review from me !!! Compass Mining has made it easy for me to mine Bitcoin !!! Wonderful people and company who are as real and everyday people just like me !!! I will be buying a third batch of miners in 2024 January !!!

Great 3 months of mining I have started with Compass about three months ago and so far I'm very happy with the service. Miners were delivered even before expected dates and have been mining since with minimum downtime. Support had been in touch with me few time and generally responds within few days. As it stands now 5 stars well deserved. Fingers crossed it will stay at this level of service.

Don't Do It! Avg 20% uptime. Just buy BTC. 3+ years in Avg 20% uptime across all five of our units. Compass Home page cites glowing reviews and guarantees, none of that for us. Zero phone calls answered or returned. Many service tickets "we are sorry" with many lame excuses but no credits for this down time, only two of five units still working. In the red big time on this very poor investment. Sorry we got involved. No response to requests for "guarantee" help, now they want me to replace units that are irreparable after they've not even worked for one full year. They should be embarrassed to keep marketing machines as if everything it okay. Place is a clown show. Some "service" tickets still going on over a year with months between correspondence. Unbelievable really. Just buy BTC.
