ROFL the price of this asic is just stupid $2500 when bitmains l3+ is 1593 right now, not worth it to buy this bw-l21 asic

You have to wait a bit for Bitmain, but you're right, the L21s are WAY overpriced for what you get IMHO.  Hyperbit lost our shipment (along with others) and was a month late. So, ordering the high priced L21, really wasn't worth it compared to Bitmain.  At Bitmain recently, we've had orders verified in 15 minutes, shipped before schedule and next day customer service.  At Hyperbit, we were refused compensation (although promised) and/or shipping refund for the month late order unless we ordered again! Lol.

I have had a recent order arrive 1 month earlier than expected from antminer!

Great, isn't it? Hyperbit's view that Bitmain's service is awful seems to be a difficult argument to support, especially when they cannot provide even location information for shipments.

Damn, turn out my transformer was not working properly on 220v, i used multi reader to verify this, get new one at local shop and working great.
Another question is, since nicehash was hacked. What is best alternative one for ltc pool?
Thanks guys for the help.

Consider BW for your L21s

Clueless!
I used to mine at Nicehash.

I'm now mining at Prohashing.com


to tell you the truth...I'm not sure if www.prohashing.com now is doing any better than www.litecoinpool.org

at 101% payout and no fees.

using this calc (which has 101% built-in) www.litecoinpool.org/calc

With bitconnect no longer a POW coin and everyone piling into LTC...it may be a draw!

I used to make 15% to 20% more a day on prohashing..but them days seem to be gone ....

I just received my order today, thankfully it's on time shipment.
I tried to plug it in, only power supply power up (i use power supply that comes with miner), miner itself no light no fan. Am i missing something to power up the miner?
Anyone has this issues? Am i missing something?
Thanks
More simply - make sure that you are using 220V or a voltage that matches the input requirement for the PSU. It sounds like you may be trying to power the PSU with 110V. Hyperbit support was supposed to ask you which voltage you preferred prior to shipping.

I tried 110v, i tried 220v, neither works Sad
Would it be some losing cable inside of miner?
When you power up, the miner automatically turn on or you have to hit reset button?

All connection are good. So, the power supply comes with 10 ports but the miner only have 6 ports, the question is does the port has to plug in in orders? ( i don't know which one to which).
I will get measure it tomorrow when i get one,  

As long as those six ports in the miner are powered, you are ok.
There is no specific connection order for the cables.
And you don't need to worry about spare pci-e power cables.

Also the PSU input is 180/260V AC, so i have to use 220v right?
Yes.

Can you doublecheck that the connections are ok and can you measure if there is a 12V output from the power supply? (you need a multimeter for this)

notey

     Tested for 180 days!!!!

     This seems like a new regular thing.  I can't help but feel that some of these companies treat individual customers (and small business customers) like dealers selling to drug addicts.  "you'll get it when I say you get it"  and yes, include the 'stomped down and cut' metaphors for lost time and profits.

Well, I just got off of the phone with UPS. Mine originated from Springfield Gardens, NY. My boxes are 26-27lbs a piece, so I'm assuming I'm receiving 2 miners per box. Are you on the east coast or west coast?
I was told that there were 2 miners per box.  Mine are listed as being a little heavier than yours for some reason.  We are on the east coast, mid-atlantic area.  Your labels originate from NY, no telling where they actually are right now.  I asked for a tracking number that showed the current location of miners, but was never directly answered.  The Hyperbit employee I've been communicating with has had IP addresses from Australia and Seattle Washington.  I've been ordering additional L3+ miners from Bitmain since there isn't  a lot of transparency in this process so far.  I hope it gets better soon.  Like you, I saw that BW was listing them as distributors and that's why we started buying.

Sounds a lot like as a distributor they got the miners early. Perhaps same time as the OP also
Got his say more or less on his evaluation unit and they have been mining the hell out of them as
The distributor.
What aggravates me the MOST is that it looks like we will get them around the end of Nov and about the same time as Bitmain would have sent the L3+.  I could have ordered from Bitmain and paid half the cost.  The only reason I ordered these was b/c we were promised fast shipping.  Won't make the same mistake again.

I am very sorry to hear this

Just saw this reply on Twitter from @hyperbitshop.  Looks like they are blaming shipping delays.  Called UPS and FedEx who both told us that there were NO current delays. You can't say that you "ship on time" upload a non-working tracking number and then blame the shipping company.  Looks like Hyperbitshop has a lot to learn.  Not only about the shipping process but about their customers, too.
Replying to @razethemaze
Yes, they have, but there are some shipping delays to the USA, due to the time of year. We are doing everything we can to speed things up.

Yep...it takes time to take the miners down after using them for two months....air compress the dust-out.....pack them up with all the proper doc's so it looks unused (damn, where is

that original packing slip)....load them all up and drive them down to UPS and/or fed ex..and as was stated in a previous post... ship them to original customers from N.J. and was it Arizona?

I've no doubt..this is the bottleneck from China to you.....mining trickery.....





Trickery, yes.  We ordered a number of the L21s based on the rapid PROMISED shipping time.  We paid right at $3000 USD each for the miners for batch one, once you figure PSU and shipping costs.  We have been running them for about ten days or so and I wish I had never seen one of these.

Since they were a month late, we had already been losing money on the miners depreciating against scrypt difficulty levels.  Hyperbit did not volunteer to refund shipping for batch one but during the time that our shipment was lost (yes, we could not find them) Hyperbit offered to "compensate" us for the lost mining time.  Ha! Just heard that this warm gesture of customer appreciation will only be extended as a credit against future orders!  The customer service is laughable to say the least.

Once the miners finally arrived, we put them on the rack next to our Bitmain products.  They are so loud that they drown out everything else.  88 decibels on the meter.  If you are putting these in an area where people work, you should provide them with hearing protection for sure. 

Now, we are having hashrate issues.  The other main draw for these miners was the hashrate, advertised as 600 MHs at frequency 684.  They get nowhere close to that.  When I opened the miner interfaces for the first time, it showed that the miners had been hashing for 180 days already.  The dashboard shows 585 MHs but most pools are clocking us below 500 MHs.  There are some hardware or firmware issues that are at play here.

I don't believe that Hyperbit is proactively attempting to address concerns.  Their leader attempts to argue with you instead of problem solve.

That's just my humble opinion after my small fry order of $40,000.

Hi everyone

On behalf of Hyperbit, the global distributor for the L21 Litecoin Miner, I would like to acknowledge that a number of USA based customers (7 in total) have been affected by a shipping delay to their recent orders. All other customers for the October 30th shipment have received their L21s.

We have been in regular direct contact with those customers affected to let them know about this and we sincerely apologise for this unfortunate and unforeseen delay. We are doing everything we can to expedite the delivery of the miners they have ordered and will continue to provide direct updates to the customers affected.

If anyone else, other than these 7 customers we have already been in contact with has any queries then please do not hesitate to email me at [email protected] and I will respond immediately.

Best regards
