Review on Ajax Scientific 🔍 Bi-Convex Spherical Double Lens by Neil Biondo

This item was exactly what I wanted but the one I received has a small scratch/dent right down the middle so I'm not sure of the overall quality. In the picture they also look like they are oval, but they are round. Not such a big problem as the cost of doing this is minimal. I will probably return it and hope it doesn't get scratched. free!
