Thanks for the review.
I have an Angelbird Wings PX1 myself for about 6 month now and I'm mostly satisfied with it.
It has a superb build quality and performs equally superb (the Samsung 950pro 512GB in it of course).
But I have to say the white LEDs around the adapters PCB are just plain annoying. They are way too bright and can't even be switched off, at least not without a soldering iron or ghetto-style masking tape. The PCB itself is yellow, but painted black. Unfortunately, it has an unpainted ring around right where the LEDs are placed, which exposes the PCBs natural yellow color. So the light coming from the Wings PX1 is either a very bright white or yellow, depending on the angle you look at it. And it is an ugly kind of yellow which just does not fit any particular color scheme one could have chosen for the innards of its PC.
For a piece of hardware that costs 80€ here in Europe, I would've expected better. At least a small jumper to turn the LEDs completely off would've been nice.
Another minor point of criticism has to go to the mounting screw: In the retail box I received was a simple M3 allen key screw and a complementing nut/spacer which is supposed to double-function as both, the spacer to ensure proper distance of the SSDs PCB to the adapters PCB when mounted and a nut to secure the screw.
Unfortunately these 2 parts alone wouldn't hold the SSD securely in place, since either the nut/spacer can be used as a spacer (mounted betweed the adapter and the SSD or ontop of the SSD as only a nut, but then does not work as a spacer.
The first variant does not hold the SSD at all, while the second variant just puts too much force on the SSD and bends it towards the adapter.
Maybe they just forgot to put the missing second mounting nut in the package on the early versions, who knows?!
Again, for a piece of hardware that costs 80€, I would've expected better.
