### ⭐⭐⭐⭐⭐ They do exactly what they should, hold and distribute heat
*by  on Reviewed in the United Kingdom 19 June 2025*

I’m so glad I found these lava rocks, which were bought to replace old bbq rocks. They have worked extremely well, hold the heat and do exactly what they should

### ⭐⭐⭐⭐⭐ Cut down on the charcoal.
*by  on Reviewed in the United Kingdom 11 July 2026*

These are great, our bbq is a large dome type and needs a lot of charcoal, with these in can get away with half the amount now with tremendous heat.

### ⭐⭐⭐⭐ Good
