Using these for cosplay. They were smaller then i thought but work really well.No scratches no cracksWould recommend

Not good for taking images through. Band of imperfection right through the middle of the dome makes it useless for accurate image taking.

Good dome, a bit irregularities in the surface but overall very clear and uniform. The dimensions shown in the picture are wrong. I estimated the diagonal center to center distance as being 89.75 mm. This was based on a measured edge to edge of 85.5 mm and a hole diameter of about 4.25 mm. Likewise I estimated the distance to each nearest hole as being 63.5 mm. This is based on the measured average distance of 59.25 mm and a hole diameter of 4.25 mm.

We used this to make the belly of an animal bank. It's very sturdy.

The dome distorts images taken with a camera. This causes portions of the image to be out of focus. The effect on image quality makes it useless as a protective cover for a camera.
