Terrible Company Miners are constantly down, repairs that should take a week take literally 3-4 months, they've moved my miner twice, once without my permission... Now, less than a month after they charged me $500 to repair my miner they send me an email telling me they will not allow me to renew my contract due to "market conditions and miner age"... scam!

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 !!!

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.

Smooth and easy equipment upgrade… Smooth and easy equipment upgrade facilitated by Account Manager Colby Noe with good communication from customer service throughout. Zero downtime in my hashrate!

Took a very long time to get miners… Took a very long time to get miners online. Electricity price kept increasing. They took miners offline and kept the mining proceeds, but expected me to pay for all the electricity during that period. They do not follow the law as to UCC remedies.
