@notey
They have had few different batches with different shipping dates. Which batch did you guys buy?

[Mr_Snipes]

Well, the power supply that was delivered with this miner and is included in this review, was a bad quality one.

I also needed to disassemble the miner, remove the motherboard that has the power connectors, and then send it for lightfoot for repair since he's got the skills and equipment needed for the replacement job.

eww that must smell ugly. I thought most PSUs have circuit-breakers that prevent such a literal meltdown.
How much will the whole repair-operation cost you ?

I'll report the cost when he has done his magic with it.

Notey,

We purchased quite a large quantity from them. I was given a couple of excuses on why they weren't sent out on October 31. I hounded them for tracking and finally received tracking on 11/07/2017. It says multiple packages and the weight its all correct. I am in the same boat as you. It just says "order processed: ready for UPS" Let me know if you get any updates on yours. We were hoping to buy on a monthly basis with Hyperbit since they promised 5-10 day deliveries every month. In their defense they have at least been responsive to my emails, but I gave them a lot of money and would like the products delivered on time!

I may be remembering this wrong. But thought these units, YOU had to do shipping? Why
I passed. I’m likely inncorrect, but it nags at me. Just in case FYI.

[jgthree]

It included free shipping. I mean they have created the labels for all of our units, but haven't shipped them. It doesn't make sense, and they are blaming a 3rd party logistics company. I hope the tracking updates this week

Don't know about yours, but our Fed Ex shipment also originates from Chino, California.  The miners are actually shipped from Shenzhen, China - so, not sure about the hoops there.

[jgthree]

Yes, ours says UPS Ground which I thought was a little odd, considering it's coming from China? I assumed it was being flown in through some cargo company and dispersed to UPS. I could be totally wrong.

I can't see where the label was originated. I mean BW.com had them listed as a reseller so I trusted them. My honest opinion is they are legit, but I think they are being used for a month and then shipped to us. I could be wrong, but that is my gut feeling. I'd like to think I am still going to receive our units.

Out of curiosity, what was the weight of your packages?

31.6 pounds for two miners and 2 PSUs (2 units per box).  It seems like they are sending the US miners to the west coast and then into delivery channels from there.  I think we will likely get them.  I just think it's going to be much longer than anticipated.  Please post with any additional details/questions.

[jgthree]

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.....

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 support@hyperbitshop.io and I will respond immediately.

Do you do cash sales in person in nyc?  can we pay in crypto?

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.

[omgcoins]

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

[HagssFIN]

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)
