What our customers say

Looked at the same model on three other sites. Hashboard temps are even, all three boards inside 4°C of each other. Solo hopes are zero but that isn't why you buy one of these. Payment via BTC went through in one confirmation. Second time I've done business with Bull Miners, both smooth.

Delivery to Germany took eight days door to door. Power draw is consistent, no surprise spikes. Another Bitmain for the Bitcoin side of the fleet. At current hashprice the payback maths still works if you have cheap power. Card payment worked first try, which is not a given in this industry. Sent it to the Georgia facility — power bills are a memory. Genuinely one of the easier hardware purchases I've made.

Fantastic Bitmain Antminer S19k Pro (136Th)! Product #14279-2 delivered to Finland in only 8 days. Hashrate is excellent and BullMiners service was outstanding. Will order again.

Love my new Goldshell AL-BOX from BullMiners (ref #14921-1). Shipped quickly to Austria, mining performance is stellar. Top quality equipment.

Reliable and efficient. The Canaan Avalon A1366 130T 3250W ASIC Hitting the advertised hashrate consistently. BullMiners delivered on time. initial setup required some troubleshooting.

First unit I've bought from Bull Miners. Web UI is basic but it works. Draws 1900 W at the wall, matches the plate. ETC mining is niche now but this unit is efficient enough to make it work. Return policy was refreshingly readable. Will be back for another once I've paid the first one off.

The Antminer AL1 (15.6Th) works well, happy with the purchase overall. Stable operation so far. Small firmware update was needed.

Shipped to Portugal, arrived in six working days. Fan bearings sound healthy, no whine so far. Draws 2500 W at the wall, matches the plate. Sent it to the Georgia facility — power bills are a memory. Support was slow the first time I emailed but nailed it the second. Recommended if you know what you're doing with power planning.

Been running mine for about six weeks now. Was worth the extra for the newer generation efficiency. Goldshell's firmware isn't fancy, but it's reliable. Scrypt is the algo you want when everything else looks broken. The 1.4c/kWh rate on their hosting plan is what makes any of this profitable.

It's living in a colo rack, not at home. Auto-tuned itself to the right frequency inside an hour. Their installment option is what made the purchase possible for me.

Shipped to Portugal, arrived in six working days. Immersion setup was a bit involved but the unit itself is fine in fluid. Merged LTC/DOGE payouts arrive together, no messing about. Warranty terms were laid out clearly on the site, not buried. One of the intake grilles had a scuff, purely cosmetic. Happy with the whole process.

Was on the fence for a few weeks before pulling the trigger. Happy with the whole process.

Was a bit nervous about ordering hardware this size online. Firmware update pushed on day one, worked without bricking anything. Reading 6Gh/s steady on the pool. Customs paperwork was already prepared, courier just needed a signature. Would encourage a friend to buy from here.

Was a bit nervous about ordering hardware this size online. Acoustically nowhere near a standard Antminer, night and day. WhatsMiner's firmware isn't fancy, but it's reliable. SHA-256 machines all look the same on paper, the hosting cost is what actually decides it. Their installment option is what made the purchase possible for me. Running it under their hosting plan in Iceland, first payout hit on schedule. Would have loved a spare fan bundled in — small nit. Not a beginner box but a great value for the tier.

Was skeptical at first but the Canaan Avalon Nano 3S proved itself. No complaints about performance whatsoever. Packaging was professional and secure. Top marks across the board.

Was on the fence for a few weeks before pulling the trigger. Firmware update pushed on day one, worked without bricking anything. Draws 1280 W at the wall, matches the plate. I ran the numbers on three calculators before ordering, all landed close to the site's own. Shipped from the EU warehouse so no import duty surprises. Recommended if you know what you're doing with power planning.

Straight-forward experience from checkout to plug-in. Recommended if you know what you're doing with power planning.

It's living in a colo rack, not at home. Runs quieter than I feared, no worse than a small vacuum. WhatsMiner's firmware isn't fancy, but it's reliable. Payment via BTC went through in one confirmation. Second time I've done business with Bull Miners, both smooth.

Good performance from the VolcMiner D1 Lite (14Gh). Setup was straightforward with the included manual. fan noise is a bit louder than expected but BullMiners support was helpful in resolving it.

The listing was actually accurate for once. Runs quieter than I feared, no worse than a small vacuum. Reading 2Gh/s steady on the pool. Getting into ALEO now vs after mainnet matters, this thing helps me be early. Even split the payment across two methods without any drama.

Came double-boxed with all the accessories. Fans are loud, no getting around it, but that's the coin's problem not the vendor's. Draws 1550 W at the wall, matches the plate. The Zcash algo hasn't been touched in a while, so I feel OK about a multi-year hold. Even split the payment across two methods without any drama.

Ordered on the strength of the profitability page. Runs quieter than I feared, no worse than a small vacuum. Merged LTC/DOGE payouts arrive together, no messing about. I emailed the ops team on a Sunday and got a reply on the Sunday. The PSU cables are a hair short if you're rack-mounting. Better experience than I've had with two other shops I won't name.

Thrilled with my DragonBall purchase from BullMiners. Superb quality. Mining output is impressive. Definitely buying from BullMiners again!

Average experience overall. ElphaPex DG2 18Gh/s 3960W Setup was straightforward with the included manual. I had to contact support twice before getting a response, but they were helpful when they replied. Support team could be faster to respond.
