I bought one in 2018 and I love it.
Cons: They aren't cheap.
Pros:
- They make a great fire. Having a fire in a pit like that feels like a compromise to me, but sometimes we go places that don't have a pit or a decent ring. If we're just going to be there one or two nights, we'll use the Solo so we don't leave a mess.
- No mess. That tub is like a crematorium and all that's left of the wood is an inch or two of very fine ash. As long as you don't mess with it and don't add any water or sand, it will burn down to nothing and leave you with cool ashes that you can safely dump in the bushes. But if you try to put the fire out with water/sand, then you'll have a horrible mess on your hands.
- Incredible customer service. I called them after I thought it was out of warranty and asked them for a price for a replacement canvas carrying bag because mine had worn out. The rep wouldn't send me to sales, she said this was a service issue and replaced it with a better designed bag under warranty and sent me some other doo-dads for my "trouble". I thought I was going to get the run around, but they took great care of me.
As far as accessories go, I don't think you really need anything. Even though they call their pits a "stove", I don't really cook that way and I already have a decent grill. All you need is their stove, the ring that goes around the top lip to control the flames, and the bag. I always keep a shovel in my pickup bed and I can use that to deal with any mess from the ashes and to make a clean spot if there are dead grasses where I want to place the fire.
Besides the price, I don't think there's any downside. My buddies with their washer tubs tease me for paying big bucks when their tubs were so cheap, but mine burns the ashes more thoroughly and I don't have the same mess they do. Their tubs are pretty similar to mine though.
