If you talk about the Hyperbit shop launch, that happened already and they sold out https://hyperbitshop.io/

Price for their first batch was 2690 USD per unit.

Delivery time is same as bitmain......I do not call this making a difference in the crypto world as first stated.  I thought finally a company showed up that could deliver in a reasonable time frame.

lol....well we all need to hope for a price pump on pow scrypt and/or LTC ..It is not like I'm immune to hope that the price
goes up I have 3 L3+'s at $1,650 arriving 15th of October....

but the price of pow scrypt has to go up or even that will not be enough with the amount of equip hitting the world

anyway I limit my optimism to THREE 2 months ago....I just can't justify the prices of equip from everyone now....at this point

in time imho ....if you are betting on the price of scrypt pow coins to pump in price......you can just as well hold coins...

Anyway, maybe LTC or whatever will pump to 150 usd or something, then any of these concerns of mine won't matter long term


edit: by the by what was hyperbit's batch size hitting the world our of curiosity ...anyone know?

There being distributed by Hyperbit and also been posting updates on there Facebook page, https://www.facebook.com/hyperbitshop/, the first sale was USD bank transfer only I believe. I decided against it due to the price there selling at.

Not a clone, these L21 are well made and more reliable than Antminer L3+ miners.
I've already sent two hashboards from two different L3+ to the warranty repair.

They give any clue on the batch size..curious....from my guesses ..you can add this batch to the other 4 batches by bitmain in the wind (5 if they launch a batch this week)
at around 10k plus a batch..

my newbie dreams of mining in 2013 are repeating...betting on a price pump on scrypt pow to get me out this hole on scrypt pow miners (or at least keep it going)

I hate regressing to 2013 and newbie coin pump dreams to get me out of equipment jams....You'd think I'd moved past that..alas ...not so Sad

Did HyperBit give this miner to you to review for FREE? Or did you actually buy it?

Not questioning your integrity, but as a reader of your review i'd like to know. Asking because I would personally be more inclined to give a better review to anything or anyone who gives me $2000+.

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

Today I woke up and smelled some burned plastic in my apartment.
The worst wake up for a while.

I noticed that one of the 6-pin pci-e power cables had burned first, and then it had spread among them all.
The power supply goes straight to the recycling, I won't ever use it again.

I now bought a proper good psu this time, I should not have trusted anything less than a proper server grade psu to do the job.
I bought HP DPS-1200 FB A server power supply with breakout board and 16AWG 6-pin pci-e power cables.

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.

Here are some pictures of the burnt components for those who are interested:

Hyperbit was not involved at all in the time of this review.

We purchased 10 of the L-21s.  When we first ordered them, Hyperbitshop.io was only allowing 2 hours for a bank transfer to be completed or your order would be cancelled.  Because of this, we decided not to complete the order.  However, the CEO then e-mailed us and worked with us to accommodate a reasonable wire transfer time and also promised that if we ordered now, that he would personally make sure that the order was shipped by the end of October.  We decided to give the L-21s a chance (we already run the L3+s and have been very satisfied).  Now, Hyperbitshop has still NOT shipped our miners and we wait once again.  If I were anyone considering a litecoin miner... personally, I would stick with the Antminer product.  Less expensive and the service is no better, it seems.

Are you still in communication with the owner? 

Do you have any proof anything was ever shipped to you?

I also had someone contact me but it was so long after I wrote that I did not take it serious.
