It's running great. To my admittedly not well trained eyes the output with the P60 using the rechargeable isn't noticeably different to that on 123As. I haven't tried the P61 yet. I like the benefit light weight of the nitrolon given the rechargeable and extra section. I have a 9AN (with a B92), but it's pretty heavy. No B90 type problems with the B65 battery, it appears to hold a charge well. I basically bought the charger kit with camping/hunting in mind as something not too heavy with P6 type output that I could use without cringining about using up expensive 123As (I swear I sometimes can feel the money draining away when I use the 123As) on those mundane chores that don't merit the cost.
