I've got a bushbuddy stove, it's identical or nearly so to the Solo lite, but was developed 10+years before the Solo.
Really like it. It doesn't boil water as quick as liquid fuel or canister stoves, but it still does so surprisingly fast.
The biggest con is that all your fuel (twigs, dry alder cones, etc) needs to be right there for all your cooking time. It burns through a load so fast that if you step away for almost any amount of time, the stove runs out of fuel & the fire goes out. Granted, a load is very little material. You need to be right there actively feeding the fire.
Also, in so much as they are light, they're a little bulky as they don't collapse down.
They're fun to have when the little ones are around, as you can cook hot dogs, marshmallows, etc over the flames. The bottom does not heat up, so at home you can set it directly on a table or deck and cook.
