Review: As described, good price - It is exactly as described. Nothing wrong, nothing wowing, you get exactly what you pay for.
Review: Concave glass disk - This is exactly what it says a 100mm diameter concave on both sides glass disk just what i wanted for spinning a gyroscope and messing with light rays but the one i was sent has some chips in the edge not bad enough to ruin the function of the disk but still enough to show poor quality control

### ⭐⭐⭐⭐⭐ As described, good price

It is exactly as described. Nothing wrong, nothing wowing, you get exactly what you pay for.

### ⭐⭐⭐ Concave glass disk
*by M***R on 22 August 2022*

This is exactly what it says a 100mm diameter concave on both sides glass disk just what i wanted for spinning a gyroscope and messing with light rays but the one i was sent has some chips in the edge not bad enough to ruin the function of the disk but still enough to show poor quality control

### ⭐⭐⭐⭐ It's fine
*by L***A on 23 September 2025*

Worked well for a while, then broke when it fell from the desk onto carpet floor. Surprised given it was ~75cm drop and nothing protruding onto the glass. Oh well, wasn't expensive, it happens.
