The first was DOA. It was so terrible that my computer became unstable or failed to boot. The second works but can only read half the Blu-ray discs I put in, even new blanks straight off the spindle won't read half the time but they work great on my 10 year old 12x Lite on one Burner. It's just a little more than my 10 year old Lite on a 12x Blu-ray drive on an old p67 chipset motherboard that was just a storage farm and workhorse for years. But even worse is the fact that Google's results say this drive supports 4k UHD, which it would be if it weren't locked by firmware that intentionally makes it impossible. The drive is absolutely 4k uhd capable unless specifically blocked by firmware to prevent it.
