Need help - Found Marshydro 300w on amazon - Are they legit?

[TwoLips]

So ive been wanting to switch to led and Ive found a ZNET4 and a marshydro 300w on amazon for pretty cheap.
Was just wondering if anyone would be able to spot a fake? (As they are so cheap)
Or can I post links on here for you all to take a look at? (Not sure if im alowed)

Thanks Sara.
Just another quick question, would the 300w board would be ok for an 80x80 grow space?

Hi TwoLips, I am afraid it will be short of coverage. The recommend coverage of 60x5w is 50x50cm.
