I apply phi²=phi+1 to my devices so the error rate remains below 2% while it syncs up with my other devices, so it's so far so good. The telemetry doesn't overheat, the value for money is worth it, and the noise level is quiet. I think it's worth it, especially if you apply heat as fuel, not null

Works great. No problem with the device It has been running for about a week now. If you want to overclock it I suggest getting a different power supply, as you don’t want to use 100% of your power supply. Your power supply will get hot and can catch fire(it happens to most btc solo miners that come with their stock power supply) There are always upgrades you can do(the heatsink + power supply)

This is a very solid bitaxe miner for the category. Pros: the shipping was quick and expedient from the seller. Works exactly as described easy to set up from out of the box. Impressed to see that actually had the most current firmware already loaded and no updates were needed. Once I adjusted the pool settings and was able to properly track out of the box, it was running at about 1.5 TH/s. However, I also noted that it was pre-set up and over clocked as soon as it was plugged in it was pulling about 25 W of power in order to achieve the above hash rate. This would have been fine and I intend to put it back to the settings eventually…. See Cons. Cons: the power adapter that is shipped with this bitaxe is under voltage, which means that when it is overclocked, it runs at a dangerously high heat level and the fan is stuck running at 100% in addition the voltage drops to about 4.6 to 4.7 which creates heat issues and can be a concern across the board both for electrical and the unit. Overall, this is a quality buy, especially if it goes on sale, however be aware that you will be sourcing your own power adapter, if you wish to be able to achieve the higher hash rate without destroying the device rapidly. I would really like to see any updated versions swap the power charger out as that would be the most efficient way to be able to achieve a more productive unit.
