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.

Lack of transparency
Unfortunately a very bad experience, a frustrating lack of transparency.
I bought a miner operating in Ontario, frankly overpriced, over promises like "yes it costs more than twice the market price, Sir, but hey, we're here, we will ship it mount it maintain it etc."
Let's hold that thought for a second.
The miner remains up for somewhat year with constant downs - one maybe can expect that with all the crackdown on these mining businesses, sustainability, droughts, etc. - when suddenly just before the contract expires the miner goes down inexorably for no reason.
I'm told, after a few persistent messages, that the miner had performance problems and needs to be reconfigured: well, do it then, it's still under contract, isn't it?
"Ah no, it takes about $500 for those things to be done"
I think about it, a little pissed off, finally I tell them: yeah ok, go ahead, do the reconfiguration and bill it to me. In the meantime their sales dept shows up to propose a mining contract renewal with a purchase new miners, cause it's better performance, etc. I refuse and keep my miner on the same conditions. Why invest more if you are not already such a reliable partner?
Bottomline, the miner never comes back up, it's been almost a year since the contract was renewed, I had to open new tickets to figure out "where the hell is my miner, are you fixing it finally or did it fall into the hands of some Canadian bear?". I have no answers until I ask them to ship it to my home and terminate the contract.
Then I finally get an answer: they make me sign a withdrawal agreement from the contract and that they will ship the miner to me. Again for the usual $500 USD.
They also add "oh, and you have to pay the electricity bills until the shipping happens". Well that's going to be easy, the miner has been down for almost a year..
Anyways, I'm exhausted, I pay, and now it's two months that I've been waiting. Did the miner ever existed in the first place? I don't know. Is someone in background buying some old miner in China to have it shipped to me? Anything is possible, frankly. One thing I'm sure of: they won't see my money again. And you should be careful as well.

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.
