Review on Round Double Convex Optical Purity by Vedprakash Trilltight

Revainrating 4 out of 5

Good for reading, bad for starting a fire.

I bought this to start a solar fire. It magnifies well, but compresses sunlight very poorly in a small space. The wallet-sized Fresnel lens outperformed it in the test. The thickness (rather thick) and narrower width make this combination bad for sunburns.

Pros
  • Stylish and modern design
Cons
  • Slightly wrinkled
