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.

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

I give Compass a score of 96 out of 100 Some reviewers here are looking for miracles! I have been with Compass for over 2 years and find the support exceptional in nearly all respects. If my machine is offline for >24 hours and message them. The message is acknowledged, then 19/20 I get a reply within 24 hours, and action taken in 1-4 days. Occasionally one miner goes offline and into a black hole. Then - I didn't know this till recently - they will loan you a machine till it's fixed. If you get stuck with support, phone them - hunt around and there is a phone number for sales. They'll help. Overall I give Compass 96/100! I am happy and see too much inappropriate moaning on here. It's the wild west: take it on the chin and see Compass for what they are - worthy partners.

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.

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.
