I have a Reo Grand with the RM2 and I'm incredibly happy with it. I was actually very hesitant about it at first, even after I bought it, as I was kind of entering the unknown, but once it came in, I absolutely fell in love with it. It's a lot smaller than it looks online, and can easily fit in my pocket without any problems. It's become my "out and about" mod. I travel a lot for work and it goes on every trip with me. It's been everywhere from Miami to Canada in -38°F weather, and was still working fine....as long as I used it before the
juice started freezing up, then quickly throw it back in my pocket, ha ha! Simply for the greater battery life and
juice capacity, I would definitely recommend a Reo Grand and RM2. I'm a huge fan.
