I have one, we use it in the fall when we sit in front of the garage and don’t feel like dealing with the solo stove. It’s on concrete driveway, and we’re probably 4-5 back from it. I’m totally comfortable using it how we do, but I could never imaging actually using one of these in the house on a table! It’s full of boiling alcohol! More on reddit.com

If it's gas you'll turn it on a surprising amount. Not the same thing but I had a wood fireplace I only used maybe 2-3 times per year because I was never going to sit down long enough to justify starting and tending the fire.

Pretty sure the risk comes from hot stones becoming suddenly wet. They explode from the rapid change in temperature.

If the stones are wet and you turn on the fire then the water will heat up and evaporate as the rocks heat up. No boom. More on reddit.com
