Easy to put together and install. Has thermal heat stuff. Even though SSD drives don't run that hot. Doesn't work with newer and smaller SSD foot prints. My Western digital 2 TB has a really small die. Only at 35 Celsius. Has 3 lights on the back. Interesting color choice, red for power. why not green ? Then your NVMe drive has a blue light and the sata one is a yellow light. Not as if you're looking at them all the time either way.

Instructions unclear about screwing down M.2 cards. Only reason I'm docking a star. How hard is it to have proper instructions ? Was number 1 concern I had was about people complaining about the screw not being long enough and issues with it. Now I realize they were putting spacer in wrong place (on back of the board) Don't put the brass spacer on the bottom. Put it between the M.2 card and the board.

I actually have 2 NVMe cards installed. Just the older one has the "sata" slot in it, so it can be put into the top SSD sata slot. It was an experiment to see if it would work. It did. I know a different reviewer said theirs didn't. So your mileage may vary. Mine was a crucial 500gb drive. From a few years ago. Was only thing I was worried about, but worked out in the end. The NVMe Slot, I put a brand new Western Digital 2 TB drive. No issues. Mines not running at full speed, compared to tech reviews. But my computer is also 5+ years old Its still way faster than any of my other SSD drives. Which are older and / or limited by SATA data speeds.

The extras are what surprised me. They included 2 extra screws and extra thermal tape depending on whether your ssd has chips on both sides or not. The only thing that would make it better if it supported 2 NVMe cards.

No configuration required, full Plug-n-Play functionality. Easy to use.

Instructions unclear on how to mount the brass "nut" so the SSD can be screwed onto it and held on the card (I mounted the 'neck' in the hole and screwed it in from the bottom. Then a screw from the top to hold the card down onto the "nut"). SATA cable (not included) and available mobo SATA port needed.

This card was easy to use in general. Windows 10 recognizes it as an Intel Series 8 chipset and with the SSD M.2 SATA card mounted BIOS recognizes it and allow selection as boot device. Make sure you choose the right slot. A M.2 SATA mounted in the M.2 nVME slot produces nothing (no drive recognized). Well worth the cost
