I bought the BC04 mainly because i wanted to use ethernet but the setup turned into a complete headache. The connection kept failing, the OS was buggy and even after updating everything i still ended up using wifi instead. i spent almost 8 hours just trying to get a brand new miner working!!!! it finally hashes now but honestly i shouldnt have to fight with the software this much just to use a basic feature

This is the part that really annoyed me, the miner arrived not working properly so obviously I contacted them to return it. Then I find out I need to spend MORE MONEY just to get a return label??? I already paid for the miner and shipping and now because the product has a problem I have to pay again just to send it back, How is that fair??? A defective product shouldnt become another expense for the customer. Really disappointed with how the return was handled!!!

The shipment arrived in record time—taking just two days to travel from America to Europe. The equipment is top-notch and works flawlessly. I highly recommend this seller.

I bought a replacement part thinking it would work with my miner but nope... after trying everything i still couldnt get it working properly. Then i found out returning it would mean more fees and more hassle on my side. honestly thats the part that annoyed me most i already wasted time on something i couldnt use and now i have to spend even more just to send it back??? really frustrating purchase and definitely not what i expected
