Zoom-hash sent me used gridseeds. They advertise no returns on their product because "its like trying to get a refund for your used underwear" Well, they sent me used underwear then...
They also guarantee same-day shipping on their website which they don't live up to.
I ordered on Apr 6. They didn't ship on the 7th or the 8th. By the 10th, they were shipping price reduced gridseeds, so they cancelled my order on the 9th and I re-ordered on the 10th. They were supposed to ship between the 10th-12th but of course they didn't meet that time frame either. They finally shipped on the 14th and gave me a $35 refund because they didn't ship on time.
I thought the OEM packaging looked suspicious because it had clearly been opened/used before (torn edges and black marks on the white foam). I was hoping they had just reused some packaging on a bulk purchase. But all of the fans are covered in dirt/dust. The undersides of the fans are dirty that can only happen if the fans are spinning. I'm appalled they sent me a used product. I have ordered from hash-master before and they took about the same amount of time to ship but at least it was a brand new, quality product. The gridseeds I received from hash-master even mine better.
Zoomhash may be a little cheaper, but I wouldn't give them any business again.
Here's a picture of Zoomhash's gridseed:

Hi Mattle!
Tried calling you earlier.
Sorry about your experience.
You did place an order Apr 6th. We had problems with verifying your address with our shipping software which you confirmed because you had a newly constructed house.
You paid for $164.99 each. We canceled the order and you were able to get the discounted rate of $144.99 for Batch 14 instead of doing the same day shipping. Saving you $240 for waiting a week.
We dropped off the packages on April 12th Saturday on the stated ship date, USPS probably did not scan it until Monday since they are off on Sunday . So our fault and apologies. But we usually ship our batches 2-3 days early as many of you guys know.
Regarding dust, it is not just you.
People who have bought from Hash-master and other resellers report the same thing here:
https://bitcointalksearch.org/topic/m.6056219and I think I can find a few more when I get home.
Gridseed does a "burn in" of all units for supposedly "48 hours" to weed out DOAs. I have a feeling that some of these units were forgotten in the burn in process when the inventory did not move as fast. I mean why wouldn't they?
The dust should not affect the performance of the unit nor the longevity, it actually should be more reliable since most of the DOAs happen during the burn in process.
As for the torn boxes, the boxes were reused from some RMA units since we received them as OEM packaged as stated in the description and had to find packaging for the loose units.
Regardless, we can compensate you in ways other resellers will not. Please respond through the emails we sent and I will try to call you again later.
Thanks! And sorry about that.
Anyways, once again, we do not self moderate on any of our posts. So there is absolute transparency for the good and bad
