Pros
- Twice the top heat of the Portable Buddy, enough for a cabin or ice shack up to about 450 sq ft
- Approved by the maker for ventilated tents, cabins, trailers and truck caps
- Shuts itself off if it tips or if oxygen in the space runs low
- Three heat settings and two cylinder inlets, so it can run on a pair of 1 lb cylinders or a 20 lb tank
Cons
- The fan was dropped on current units, so heat spreads less evenly than on older ones
- The 20 lb tank hose and filter cost extra
- No thermostat, so you adjust it by hand
- Heavier and pricier than the Portable Buddy
