## Customer Reviews

### ⭐⭐⭐⭐⭐ Very decent product and exelent services
*by B***E on March 21, 2016*

Comes with everything you need (screws and bolts and such), it even go's so far as to have 2 front plates, for shorted server boxes and normal PC case. Works very well from what the tests tell me and its quite easy to use, it comes with a manual and instructions for even the most retarded of users and even the box it comes in seems fairly well made. The only thing that is left now is the test of time, for now I can honestly say I'm very satisfied.The package was a few days late, when I tried to get answers Amazon immediately sent me another one with express shipping free of charge, the product is quite good, but Amazon's services are as always just amazing! Very fast, very considerate and very good. I don't think I have ever had a problem with them or that there is any online store (or life store) that I would rather buy from. You can really be sure that you're safe when buying from Amazon!Thank you

### ⭐⭐⭐⭐ Very poor M.2 mounting
*by D***E on March 20, 2016*

Unfortunately, my motherboard won't boot from this but that's not the fault of this board. I had to put in an SSD SATA drive (Samsung 850 EVO) for boot. But copies from the 850 EVO to the Samsung XP941 on this board happen at over 1.4GB/s. A 4GB file copied so fast I couldn't get a clear read on the speed; literally in just two or three seconds.I haven't tried the B-Key (SATA) connection yet but it works great on the M-Key.Had to go back in and edit my review; I forgot the one really bad thing about this. Their is no stud or attached nut into which you screw the M.2 card; there's just a hole. And what you get is a screw and a nut, no lock-washer. I'm not sure how long this will stay together before the nut vibrates off and shorts out something in my computer. There are many types of mounts that boards use to fit a nut that you screw into for mounting drives like this. I've seen plastic clips, pressed in female studs, soldered on nuts, etc. This has none of those. Just a screw and a nut. And the screw is not anything you can screw in. It has a flat head (not flat-head for a screwdriver, just flat. no slot) and there's a tiny threaded female hole for screwing in an even tinier screw to mount the disk. Hard to explain; I'll try to add pictures later but I don't have the extra screws available as I write this. All I can say, is the M.2 mounting is very poor. I hope it lasts

### ⭐⭐⭐⭐⭐ It just works, but for one NVMe card only
*by S***L on June 20, 2018*

This worked fine to put a Samsung 970 Pro SSD in my desktop PC. The card goes into a PCIeX4 (or higher) slot and Windows 10 picked it up without my having to do anything. The "Dual" aspect needs some care in addressing if you don't read carefully. While one M.2 slot supports NVMe drives such as the Samsung 970, the other slot will accept only SATA-interface drives and then it will work only if you connect a SATA cable from your motherboard to the connector on the card. So if you were hoping for a solution that would take two NVMe cards, this isn't it.I have no complaints about the adapter at all - it just works. I'll comment that the M.2 slots have enough room for SSDs that have components on the back of the card, though the Samsungs don't.
