Biggest scam in BTC space. Customer support is non-existent Customer support is non-existent. Takes weeks to reply, and months to actually get your miner back running. They have zero interest in keeping your miner running, but very interested in selling you a miner at the beginning. Avoid.

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.

My bitcoin miner has been "under… Update: After initially leaving a 1-star review, the Compass Mining team reached out and assigned me a temporary unit for the duration of my unit being under repair. Thank you Compass Team. My bitcoin miner has been "under repair" for 1 year now. At this point, Compass no longer responds to my messages in the ticket I started with them when I ask for a status update on the repair. Additionally, I have tried starting other tickets to get an update and they just tell me they are "merging" it with the existing ticket and don't give me an update on the repair. I wanted to support this company because their mission to bring bitcoin mining mainstream is good, but the customer support leaves a lot to be desired.

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.

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.
