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!

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.

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.

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

Such a disappointing experience
My miner has been offline for over a year. When I ask about it, weeks go by before I get a response. I have checked in consistently during this time and have had very general responses stating my machine is being fixed. How has it taken a year to get fixed? The machine was expensive and now with the halving, it is such a loss. I am so disappointed with my experience with Compass. I have gone to a different company to continue mining and have all but lost hope for the machine I have with them. They recently said they would request a temporary miner for me (though they are still waiting on a response)- why wasn't that brought up a year ago as an option?

Compassmining is a shady company...
Compassmining is a shady company with criminally liable practices. I hope my story can serve as a warning and strong deterrent to anyone wishing to give them business.
I have been dealing with issues ever since I bought miners totaling over 30,000 usd from them. I will try to list all of the shady things they have done. I will probably miss a few since there's been so many.
1. My miners went offline a few months after purchase. Customer service could do nothing for me no matter how many tickets I opened up. I was offline for 10 months. The energy rates went up twice during that period.
2. They advertise energy contracts per year, but in reality they increase rates whenever they see fit. So my monthly bill went up twice before I ever started hashing again.
3. They told me that one of my miners went from a Texas facility to Oklahoma and that it was being cleaned. It mined for 20 days and then went offline again. When I asked what happened, they said the Oklahoma operation was being shut down and my miner would be sent for cleaning again, even though it had just been cleaned. Many more months went by without hashing anything.
4. They want me to believe improbabilities like all 3 of my s19j pro miners failed beyond repair, precisely and conveniently just after their warranty was up. There's so many things wrong with this. Up until that point they had no idea where my miners were, but all of a sudden they found them and knew they were beyond repair...okay. Also, s19jpro are known to be good working miners with a very low failure rates, but they want me to believe all 3 of my new miners failed, even though they only mined for a few months before going offline.
5. They "kindly" replaced my new, now dead, miners with who knows what miners. Don't know how old or in what condition. They also stopped taking phone calls and now only answer through tickets, sporadically.
6. Some monthly Invoices do not add up correctly. Someone in customer service finally decided to investigate further...and my invoices went up even more lol.
7. When I asked for my miners to be shipped to me, I told them to remove the monthly invoices for April since they should not be mining for much longer. Each miner's invoice is roughly 180ish dollars, so 540 dollars should have been removed from my invoices. Only 378 dollars was removed. There's always something shady with them.
This has been years in the making. I have tried to be patient and understand that every company has issues, but now I sincerely believe that there are shady practices going on with this company. From the many complaints and bad reviews across different sites, there's just too much evidence. I have finally given up and they have made an enemy out of a once loyal customer. I have all the emails, from all the issues and now I will spread my terrible experience as far and wide as I can. Do not do business with this company, you will regret it.

5 months of down time
5 months of down time, since Nov 2023, and still just lip service from Compass. I can't even request they ship it back to me, location is "somewhere" in Texas. Terrible management, horrible customer service; really expensive ASIC, I will never break even on this investment. Run, don't walk, away!

50% downtime!!
I bought a miner from Compass 2-3 years ago. The number of outages have been excessive. Looking at my payouts over the past 12 months, the miner was offline for at least 50% of the year. HALF!! They had one job - keep my miner mining.
BTC miners have a limited shelf life as we approach halvlngs and more powerful miners come to market.
Compass have completely failed me.
