Credo, this is unusual, because a few hours ago I was reading up on the Boge Revolution. Is your a V2 or V2.1? In the earlier versions there was some mis-labeling of batteries I think 2.1 was when they dumped the 'negative ion generator' and went for a second batt, for 1400 Mah.
I have no experience with a feeder, but had been considering a Darwin backup as well, and was looking at this. I saw somewhere where there was a comment that it would leak on it's side. Is this inherent to a bottom feeder in general?
After I vaped with a big batt 510 enough to realize that I could indeed quit smoking, I chose Darwin after a research marathon. I mow a couple of acres regularly, and use my 510 for that. I do not want to risk dropping Darwin while doing that (Will It Mow?).
A homemade lanyard and the 510 is good enough for a couple of hours.
My Reo Grand lays on it's side just fine... doesnt leak... even with 80/20



I will know soon enough!!! Thanks
