The miners are almost always offline The miners are almost always offline. Bought 6 miners that went online about a year after the scheduled date, they mined for about 1 year (constantly on and off, almost never had all 6 online). My $50k investment turned $16k (just thank to Bitcoin price going up) and now with the halving coming up the miners are obsolete. Don’t get scammed

High prices and horrible support. Let's ignore the prices and focus on the support problems with two examples: 1.) The relocation of units from Texas 4 takes more than HALF A YEAR now and is still not resolved. An absolutely horrible experience without the possibility to chose the data center the unit is being relocated to. 2.) A brand new S19k went offline. Instead of properly monitoring the deployed units, identifying problems and fixing them right away it took Compass Mining ONE WEEK to diagnose the problem without an estimate on the repair itself. Their support team obviously has no power over anything. It's the worst support I have encountered so far.

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 !!!

Always great service. Always great service. Yes, miners have downtime due to power curtailment, but Compass doesn't control this. Compass will credit the account if a miner is down for some time. Depending on the current price of BTC, it may not cover the entire amount of lost income from the miner actually hashing. I haven't found a better hosting company, and I definitely don't want these miners running at my home, paying $0.11 kWh.

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.
