Review: They’re really good rocks 😂 - Well, they’re rocks. I combined them with two other bags of different sizes to fill in my fireplace under my electric logs.

### ⭐⭐⭐⭐⭐ They’re really good rocks 😂

Well, they’re rocks. I combined them with two other bags of different sizes to fill in my fireplace under my electric logs. They look like black rocks, which was what I wanted. Oh, they do make a mess when installing them. Wear gloves and prepare to wipe the hearth after installation.

### ⭐⭐⭐⭐⭐ Works for our portable propane fireplace.

I thought the price point was good, size works for out portable fireplace. It’s not a small one, I would say medium. They should last awhile, not too lightweight. Puts out plenty of heat when they warm up.

### ⭐⭐⭐⭐ As advertised but kind of over priced
*by M***E on December 17, 2025*

These did the job for my fire table and look great. The rock sizes are large, as stated. If you need smaller pieces to fill in areas just smack a couple of pieces in the bag with a hammer and the breakup easily into multiple smaller pieces. Pretty simple. The only thing is, these are quite expensive for what they are, which is why I’m only giving it 4 stars.
