I bought custom chrome Space Men from Lego and compatible figures from other producers.
The figures from Joy Bricks 21 are good and way better than everage. I will not comment on the price issue...

After assembly, the legs and arms are movable. The head sits tight.

The helmets are an issue, which is why I substracted one point:
There are very obvious sprue points and a line where the parts were joint in plain sight, which is very annoying.
Face prints are moderately good, but site by site it is obvious.

All in all, I can recommend the space figures.

The minifigs look great on a shelf and as part of my space collection. The quality is a bit hit and miss, as their feet don't quite fit over studs, the visors are a little misty and they are stiff to move, probably due to the chrome being an extra layer over the moulded plastic. But aside from these small issues, I am very pleased. I look forward to posing them about with spaceships and whatnot.
