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:



And here's a picture of Hash-master's that has been running for 3 weeks:
