Review on Ubit 6-Pack GPU Riser Express Cable 16X to 1X (6pin / MOLEX/SATA) with LED Graphics Extension | Ideal for Ethereum ETH Mining | Powered Riser Adapter Card by Kris Feezy

I was planning to assemble 3 rigs with 6 GPUs, of course I bought 3 sets of 6 of these adapters. 2 boxes with stand went without complaints, with the third box everything went downhill. 3 locking mechanisms popped out when trying to secure the GPU in the riser, I thought I could handle that, also the 4 risers were literally DOA. Not a single sign of life. I hope the seller reads this to help. Now my build is in the starting blocks. The only reason I bought these risers is because of the positive reviews, but I think next time I should start reading the negative reviews before I shoot! UPDATE (3/20/2018) - After I wrote my review, the seller contacted me and sent a replacement set. instantly. I checked and each of the replacement risers worked fine. That's great customer service and I appreciate that this seller supports their product 100%.
