have to report - the 100 usd offer that was eventually honoured via a new order number has actually not been honoured at all.

the full price was paid and no refund/rebate has been forthcoming.

quite lame!

From what I saw the SP31 looks to be a better long term investment, as the power usage to hashpower is lower.  However if price isn't an issue and you want the fastest beast known at the time, then the SP35 is the one to get.  Note that the SP35 won't run on a 110 line, so that may rule it out for some.

Stats so far:

What kind of glue you are using?
...

Does broken corner affect performance? My broken chip runs at 500 Hz comparing with other chips running at 650Hz

When I install those guides, I found out that one of the heatsink does not have those two drops of glue on its side, thus it can be easily tilt or shake by hands. I removed it, cleaned thermal grease, it turns out all of the chip's corner are broken. Without those 2 drops of glue, I can imagine it get knocked by each vibration during transportation



This is a weakness of the cooling system. Like Spondoolies-Tech pointed out, The RockerBox ASICs with the FCBGA package aren't suitable for mechanical stress, since its die directly exposed, and it is small: only 10x11.5mm in size.

The problem is, the heat sink is just too big for the small contact surface of the die, and it has only 2 point of tension. To make things worse, its tension is flexible because of the spring in each screw, this means it will just tilt to any direction and break the corner of the die with the least amount of incaution during install/transportation. So that's why they end up using some glue to permanently fix the heatsink on the board

And, to my surprise, the copper plate is just attached together with the aluminum heatsink with thermal compound without any screw.
They can slide against each other. This means most of the heat will be transferred to the heatsink by this layer of thermal compound, which has magnitudes lower thermal conductivity than either aluminum or copper. When installed, the pressure between them is decided by the spring of those 2 screws, and it is very weak (otherwise it will break the die)

Overall I would say this is hands down the best miner I have used to date.  The interface is extremely impressive and simple enough that I think anyone could feel like a pro.  I noticed it even has an option for plugging a usb wifi adapter directly into the SP20 to free yourself from the need of a network cable.  While I haven't tested that feature, I thought it was an awesome and unexpected addition.  I do have a few interface items for my wish list though.  The option to set your pools from failover-only to balanced would be nice and I didn't see a place to setup a static IP (did I miss it?).  The miner itself is great.  It's quieter, cooler, and more efficient than it's closest counterpart (Prisma) and is encased giving it a well built feeling.  I am definitely grateful to Spondoolies for the opportunity to review this product and I will keep my eye on their offerings in the future.  If you are searching for a miner, there is no doubt this is the best you will currently find on the market.

Taken this second. So of the first 17 threads, 11 are review threads, 2 are other ST threads and 4 are other threads. This is the definition of spam.

As of this post, 7/10 review threads, +the SP20 unofficial thread, + the spondoolies thread are all active on the front page. In part, because you are being active in each and all of them.

I'll say it again, does anyone have an objection to Bitmain paying for 50 review threads? Seems not.

... The unit has been functioning as per expectations ...

Summary
The SP20 excels in quality construction and ease of setup. Provide a good PSU and turn it on. It'll adjust itself for maximum performance, even in a hot room.  Later when efficiency becomes more important, lowering the voltage will come in very handy. Recent price drops by Spondoolies make the SP20 one of the best buys in the market.

Not yet. I'm trying not to mess with my miner during the paycoin gold rush.

So to continue this debate now we're in meta.... does anyone have an objection to Bitmain having 50 review threads (10 for each active product)? That's the same as ST did.

[/sarcasm]. I hope the answer is everyone, which highlights the need for a revised revision policy to prevent multi-spam of this nature.

There is only one way to fight this sort of spam... Other manufacturers need to also give away free mining equipment to Legendary members for reviews. That's the only way it will be fair.  

And they haven't posted pics so we can drool over their setup? What's wrong with them?

I ordered Dec 17, 2014 6x SP20     (order #3798 #3797)
Paid the same day  with EU transfer.

Order status is still unfulfilled.

Can I get them before Christmas

...
So if they will want to make pre orders for SPXX, DON'T DO IT...

How come I see ads for SP20 miners when I visit my favorite porn sites? Don't you guys know I already own a bunch of them?

If it's coming from SPT, it couldn't be spam, which is clearly non-Kosher
