I have the all-stainless steel limited run that Apollo offered, and have no serious complaints. The switches all work as intended—none of the intermittent function that some report—but their plastic construction is incongruous with the solid feel and appearance of the stainless tube.
The 18350 battery is limiting, but it gets me through my workday (and I don't mind carrying a just-in-case spare).
In terms of compactness, it isn't the quantum leap I'd hoped for—it stands just a little shorter than a Buzz Pro, for instance—but it hides well in my shirt pocket, provided I have an atty as opposed to a carto &
tank screwed into it.
On balance, I'm happy with it—knock on wood.
