As far as I know Jiify is the only manufacturer of a propane auger.
To the list of "Pros" I would also add... starts 1-2 pulls every single time...no choke no prime.
With sharp blades it is not slow cutting, however, I've seen conditions where the two center chipper blades get "packed" with a slush/snow mixture and must be cleaned out or you'll get nowhere. There are probably faster cutting augers out there if you're planning on racing.
They are heavy which is definitely a "Con". I don't carry this thing hole to hole, I put it in a sled and pull it. I expect they will be shedding a few pounds in the next couple of models.
Overall I'm happy with my Pro 4-10 except for the weight issue. I still believe they are just too "young" to give it a proper review. This season will be the 3rd year for this kind of technology. Propane motors run clean and with proper maintenance/storage should last many, many years. Time will tell how the other components ( regulator, gears ) hold up after hundreds of hours of use.
Hope this helps.
