Review on Eisco Labs Acrylic Light Pipe: Illuminating Innovation for Precise Optical Experiments by Jon Garcia

The performance of this item is disappointing compared to glass tubes. I gave away a few I just bought as a gesture of goodwill in the hope that someone (someone) with no experience with glass and therefore without glass as a benchmark might like them. However, I doubt anyone will enjoy these devices for long as they lack the wow factor of glass light guides.
