Ouch that's scary. I've sold about 8 S3's and 3 S5's on ebay. Never had one returned so I've been lucky. In fact I plan on selling my last S3 and S5 on ebay once I get another S7 to replace them. Hope I never go through your experience. Their fees really are the rape, though.

I've sold 44 rigs on eBay. The last one was sold and shipped the first week in September. I sold 18 x S3's, 15 x SP20's, 5 x S4's and 6 x S5's. All but one S3 sold according to schedule. I had to re-list it because the buyer did not pay. It has been 45 days for most of them now.

I purchased my S3+ on ebay and it has been a rock-solid machine for almost a year now. I run it slightly overclocked to get ~500GH/s and it performs like a champ (solo lottery machine).

Well, today was the first time for my internet to go down since I've had my Batch 1 S7's [9 in total - 10th on the way; it's a batch 5]. My internet was down for approximately 20 minutes while a technician was working on the main line in the neighborhood. All of my rigs began beeping shortly after the internet went out and beeped the entire time until the modem was back online. However, one of the nine S7's had a red light and was not accessible from the browser. It began working properly after I turned off the PSU and turned it back on. All are hashing properly now.

So, all in all, I'm well pleased with all of my batch 1's.

EDIT: I do get a whistling sound from one of the S7's. I've put a piece of tape over a small portion of the fan at the bottom and the whistling stopped.

Maybe you missed them, but some folks have mentioned that a a "slight loosen" of the fan screws have cured their machines of various fan noises. Might be the equivalent of the tape you applied.

Just a thought to consider.

I already did this when I first got them to reduce a high pitched sound. This new sound started after my internet connection came back on line and they started hashing again. It's like the wind sucked in the fan is whistling as it goes between the fins of a heat sink towards the front of the rig. If I held my two fingers up at the bottom center of the front fan, the whistle went away. So, I put a small piece of tape in that one spot to stop the whistle. It's weird... I'll go back downstairs after a while and take it off to see if it continues whistling.

Ouch...

Bitmain really should change some policies. I ordered several batch 6's at $1625 each. And now batch 7 w/ 5th shipping the same time mine are, arg.

If they were going out a month after or even two weeks i'd understand more. Not much I can do but vent a little.

batch 7 up?

YES. Just check www.bitmain.com for the specs. Yet another variant of the S7 specifications in terms power, cost, speed, etc. Looks to be priced in BTC.

My Internet went down before i woke up this AM.

My S5s came back online when the internet came back up...but my S7 (batch 1) didn't. I can still see it when i check it thru my LAN. All the ASICs are there and have all 0's but there is no hashing. The fans are running too.

I rebooted. No change. I switched PSUs - still no change. I did a few reboots- no change. Then i reset it to factory settings- still no change. Finally, i called Bitmain in Denver. The tech guy used chrome remote desktop to look at my kernel log , miner status etc. Then he shh'd into my rig. He couldn't find a problem either.

So I will be contacting Bitmain to see what can be done.

Has anyone else had this problem?

I have this issue, go into Network>Diagnostic and then ping something. Go back after a minute and check if it is hashing.

Tried that already. The ping was successful but still no hashing.

Someone analyzed my kernel log today and replied with this:

"this looks like memory problem with your beagle bone black
change it with another BBB or find S5 BBB and reflash it for S7"

i just sold some gear on ebay.. had a promo for $5 max final value fees and 30% off final value fees (whichever they decide to let me use)

buyer is located in another country but having me ship to an in country address (which is what shows on the paypal purchase details) and paypal shows that i am seller protected after they reviewed the payment. buyer mentioned he does this to circumvent customs fees by having his friend ship the units to him (probably listing them as very little value on the customs docs)

I made sure to add signature confirmation and took pics of the units as i was packaging them up

crossing my fingers it goes well, the buyer literally bought up the majority of what i had listed FS for a big chunk of $ which was kind of odd but we'll see

Return scam is much less likely with a foreign buyer (would cost them a lot to ship it back) but make sure to save those signature confirmation PDFs... the payment may turn out to be "unauthorized" 6 months down the road.

I don't think that is true. You are not providing a warranty on used gear to work for 45 days. This is from ~~paypal~~ ebay:

http://pages.ebay.com/help/sell/return-policy.html
Important: Even if you specify "no returns accepted," under the eBay Money Back Guarantee the buyer can still return an item if it doesn't match the listing description. Learn more about what the eBay Money Back Guarantee means to sellers.
http://pages.ebay.com/resolutioncenter/BuyerProtectionForSellers.html

This is what it says on a listing when the seller does not offer return:
Seller does not offer returns. You are covered by the eBay Money Back Guarantee if you received an item that is not as described in the listing.

you are just being naive about it. the buyer does not need to elaborate on anything. "the item is not as described", no questions asked. what you described is a miner that hashes as specified. imagine the buyer having shitty PSU, then doing something inane in addition. case closed and you lose.
You can try to fight it, but will lose review in most cases-just ask around.
It is better to simply refund and hope that the item will be returned undamaged.
However, I don't think that the majority of buyers on ebay are unfair, but the higher is the price, the higher a probability of a deal going south, I believe, although I don't have hard numbers.

I see. So your interpretation of the ebay policy is for some reason a fact? Who says no questions asked? Besides you I mean?

Like Marvell1 I have sold (and bought) quite a bit of asic gear on ebay and never had a problem. Maybe I have been lucky. But you can be damn sure if it came to a forced return I would expect the customer to explain in detail why the listing was not as described. Having never had a problem I can't say what that would look like in terms of dealing with ebay arbitration but if they can force returns on sellers just because the buyer says so without any questions I would be pretty surprised (to put it mildly). Courts have a way of making these kinds of policies unworkable unless spelled out really clearly. They spelled out really clearly in both the policy as well as the listing that you can only return if the item is not as described. I am inclined to go with the actual meaning of those words as opposed to your interpretation that it means return anything for any reason.

see the OP above ^^^. You can fight it, but if you don't issue a prompt refund (at least after getting an item back), it would affect your seller ratings.
Everytime I sell something on ebay, I prepare for a return, which is not a good feeling especially since they simply take $ from you regardless of your opinion about it.

yeah great points not that i am a big fan of ebay I hate thier fees and i see them as leeches, however i have had far more lucky selling stuff on EBAY than here and lightcointalk , Ebay allows you to reach a larger percentage of people who actually are not tire kickers and really want to buy something.

In regards to returns i think on disputes ebay weighs your rep as a seller vs the buyer. Ive had a buyer try to claim that they did not recive an item i shipped and ebay took my side based on my history and ratings. So i don;t think its a cut and dry as "buyer allways wins" if you are not selling alot on Ebay I get a feeling they pennalize you in these kinds of circumstances.

One interesting thing to note about ROI is that for some reason bitcoin miners have an unreasonably high resell value on ebay. So an S7 in hand today (or soon) doesn't have to mine the full value back if you can resell it and:

resell amount + mining returns > cost + expenses

Of course with the halving coming up there may actually be a glut of miners hitting the resell market next year some time so timing a sale might be part of the equation if you go that route. But it's hard to predict what the halving will actually do. I would have thought the LTC halving would increase the value of LCT but it didn't really. If BTC follows the same pattern then mining will get much less profitable.

what is ebay return rate, i wonder? also, once you remove 13% fees, there is not much profit there either.
It seems that $400 level does not induce much fraud on ebay, but i don't know if $2000 does, especially since a buyer can make a mistake, then return for any reason at all.

theres options on your listing to select no returns.. also if you mention no returns in the listing as well thats twice being mentioned returns not offered.

can a buyer still return them after that?

Yes they can by claiming that the miner doesn't work within 45 days or PayPal refund window. You have no choice but to accept the return.

I don't think that is true. You are not providing a warranty on used gear to work for 45 days. This is from ~~paypal~~ ebay:

You probably didn't had to go through eBay return process yet. This is from my experience, I sold B1 S7 on eBay after 40 days buyer started a return process on my no return eBay sale. I was given three choices :

1. Issue a return label at my own expense
2. Issue refund now or
3. Issue refund after receiving the item.

Not much choice.

Really? You're not even buying bitcoin anymore? It's easily going to $700 [Minimum] in my opinion just before the halving. Even if one thought it was going to $500 or $550 minimum just before the halving, it's worth buying on the next dip and hold until it gets to $500 to $550 [If one has the funds to spare in buying it].

Really hope you are right.

Would be interested in your theory as to why will see a rise, and why just before the halving?

We know that 1/2 the number of coins a Day will then be mined, but why does that mean the value increases? Also surely if there is a rise "Due" it will happen way ahead of the actual event?

To be very honest, wifie complains that i overspent "our" money recently, and I somewhat agree as I spent quite a bit on B1-B6 (been greedy Grin

They will provide a bitcoin flow, hopefully, so i don't have to purchase more for cash and instead buy or lease her a Mini that she wants.
