tim the two from the kit didnt run very hot at all...if marked as reg. atties i would understand but i used them and then an lr510 and then another and definitely a huge difference. i would say a decent performance if they were regular atomisers but if you like lr attys then you might be disappointed. i remember you mentioning lr but these dont seem so to me....the performance has been constant from day one neither have died on me but i wouldnt have used them all day as i prefer the heat and t.h. from an lr510.
love the battery though huge thumbs up on all counts...looks, performance, durability....
I doubt i will use both atties to death in the near future if you would like i can send them back to you to compare with others or send back to your manufacturer to test?
