## Customer Reviews

### ⭐⭐⭐ Product is wonderful
*by A***  on September 7, 2023*

I can’t say enough good about the quality of this base rock, and ease of working with it! I would give it 5+ stars, but when dealing with customer service, and reaching out looking for a response, I have never seen worse! I love what this company does, and the rock is so easy to work with, but due to delays, I had to attempt to reach out several times. And I used multiple different methods of reaching out, all to no avail. Their response time is pretty atrocious. But when I received the rocks, it was worth the wait.

### ⭐⭐⭐⭐⭐ Better than expected. Would buy again
*by A***I on November 15, 2022*

Very nice array of rocks. Extremely porous and holy. Acrylic connecting rods came in handy as well. Drilled holes added stability and was able to make a nice shelf and caves. Goby lives literally inside the bottom of a rock through the network of holes. Would buy again for another tank.
