How It Compares With Other Options
An honest read on the trade-offs, so the material decision is made before fabrication starts.
| Plastic HDRI ball | Plastic is lighter and cheaper but less durable; Kapur's ball has more surface treatments for consistent reflection |
|---|---|
| Metal chrome ball | Metal offers better weight and heat resistance but may scratch; Kapur's ball has multiple treatments to maintain finish |
| Mass-produced reflective ball | Mass-produced balls often have inconsistent finishes; Kapur's ball is hand-treated and tested for professional use |
| Painted gray ball | Painted balls fade and chip; Kapur's gray finish is tested over time for long-term consistency |
