Not so good. Its very expensive, its not worth it. Not recommended for practical buyers. Mining should not be expensive as this one or maybe you will need a very high specs in order to mine well using this.

Butterfly labs equipment is extremely expensive for the price per GH. You would barley make a profit from mining bitcoins. Go somewhere else.

expensive yet not profitable to mine bitcoins due to high dificulty so please lower the price per GH

They were one of the first (first that I saw) ASIC manufacturers, I ordered 4 x 5GH/s jalapeno devices in Aug 2012, later upgrading to 1 x LITTLE SINGLE 30GH/s unit. MONTHS AND MONTHS OF LIES ENSUED from BFL, stating a plethora of problems encountered by them... their fab and every possible excuse under the sun... probably ALL excuses were used EXCEPT the sun... Anyway, I gave up and figured I was scammed! August 18th 2013 (yep, that's OVER A FULL F***ING YEAR!!!) I noticed they were shipping to my purchase date, but no email telling me mine has been sent, or even that it is getting close... EVENTUALLY after some emailing I get a confirmation email saying my items has shipped. NOT BEFORE CHARGING ME AN EXTRA US$100 for EXPRESS shipping?! If the device was ready a YEAR AGO I wouldn't NEED express shipping. Device ACTUALLY arrived and I started to hash... I emailed them about a slowness and I actually got a reply fairly quickly, turns out it was their stupid EASY MINER software that was to blame anyway. So BFL announce the MONARCH... really?? 300/600GH/s and 1000s of BFL customers are STILL WAITING FOR THEIR 5, 25/30, 50/60GH/s devices... Then it's CLOUD mining... What have they actually done that was GOOD (or seemingly) for the customers?? 1*. They gave us CHIP credits...<????!> a useless notion that gave us the ILLUSION that we have some credits that we can use down the road a bit (should we ever trust BFL again) * = Minimum 100 CHIPS PURCHASED PER ORDER (I had a total of 16 chip credits) + WTF can you do with ASIC chips that are not built into a system? NOTHING that's what!!! 2*. 25% DISCOUNT VOUCHER - This actually sounded like a good thing! * BUT YOU CANNOT USE THEM IN CONJUNCTION WITH ANYTHING ELSE. ie. you cannot use your CHIP CREDITS and DISCOUNT VOUCHER together. Thus I started emailing them, why can I not use my credits? It was about this time my 25% DISCOUNT VOUCHER vanished from my account... So I email AGAIN, Where's my voucher? Why can't I use chip credits? AFTER ALL, these were both things GIVEN to ME by BFL for THEM SCREWING ME AROUND! I think it was a month or so later, by this point I had given up on BFL anyway... I got an email from BFL_Josh, one liner saying "You don't need voucher anymore as prices have been dropped!" WTF!!?? So to SAY THANKS to your early customer, you DANGLE A CARROT in front of them and then throw me into the same priority queue AS EVERYONE ELSE! *** NO MATTER HOW ENTICING BFL MAY SEEM - >>>STAY AWAY<<< ***

I have personally purchased a miner from Butterflylabs. I got the Miner and it worked just fine as promised. It was at a certain cost however, meaning, it was easily a year or more late in delivery. This was after a dozen or so, changes in the promised delivery date. Also, to this day Butterfly Labs charges an arm and a leg for the Miners they Produce. The calculations on Profitability with these machines is Less Than Zero, even at Bitcoin value of $1,000. If you really look into the message boards, you will quickly notice its just a place for people to complain and comment on the many bad stories about Butterfly Labs.

My (not yet bought) number 1 is your number 2. My only experience with ASIC was horrible (Buttefly Labs). See my experiences here: http://scforum.info/index.php/topic,8398.msg21456.html#msg21456 So it looks like you're on the right track ; -) And I LOVE the overview of all ASICS out there...! ... Peace!

BFL's prices are not bad, but what they're really known for ist that they manufacture some of the most popular Bitcoin mining hardware in the world.

So to start with the good news, they are actually shipping. They are shipping 7-8 months late! Now the bad news: you will NEVER profit or break even if you order today. They constantly lying about shipping estimates and barely give you any information on when will you be able to hash with your bfl device. If you are stupid enough to pay with bitcoins, you're screwed! Refunds will never happen because they make sure you won't profit at all. No information, no refunds, no apologies or compensation for your lost hashing time. Refunds only happen if you pay with fiat currency (paypal, bank transfer and such). Many of us think that they are mining with your hardware for a long time and then you'll get used devices that they call new. 7 months burn-in to make sure it works, lol... And that's probably true because the fan issue is a dead giveaway. They just clean the boards and the cases so they look as good as new, but they're gonna fail before you break even. They charge extra for upgrading the firmware to a more efficient one and you void the warranty if you reflash it yourself. About their devices: the build quality is really good, nice finishing, but the cooling fans are some cheap bullshit designed to fail and also extremely loud. Worn out bearings, perhaps? I mean there are 4 fans in my PC, all of them are running at max RPM and my Jally is louder than all of them. If someone is reading this and is new to bitcoin mining, there is only one thing I can say: DO NOT BUY THEIR DEVICES, YOU WILL NEVER PROFIT! IF YOU WANT TO BUY ANYWAYS, BUY IT FROM PEOPLE WHO HAVE IT IN HAND! NEVER SPEND ANY BITCOINS ON BFL WEBSITE, IT'S NOT WORTH IT!
