Hey gang, just checking in here on the AW IMRs
They definitely don't last forever, but they do work well. When they are about to go I always end up with a flooded atomizer

I say this because for 10 months I've been dripping with 510 atomizers. With the GLV2mini and the IMRs I really burn through juice. Faster than I did when the AW ICRs were new. It seems like I'm always looking down and the atomizer coil is glowing like the eyes of a golem, asking for more drops. Well, I got the feel for the increased vapor/hunger with the new batteries (same atomizers) and have a steady dripping groove now. At some point I'll have a few puffs where it seems like the unit is getting dry again, add a few drops, look down and there's juice on my hands. The interface between having good performance and no performance with the IMRs appears to be very brief
I do a lot of work from home and on top of that I'm pursuing some new certs so I spend a *lot* of time in front of the computer with the GLV2mini plugged in (to my face). So far 2 IMRs get me through the day just fine. It's usually early-evening when the first battery goes. My old AW ICRs would be on constant rotation through the charger and the GLV.
I'm happy with them so far. I would definitely suggest them if you're going to buy new batteries and cost isn't a factor. To really say they are better, though, I would have to buy some new AW ICRs to compare to
