No we don't spit on folks hereIsaac want's to know if an atty is not coming in on spec or very close to intended spec. It is not uncommon to have a slight deviation, but a large one e.g 2.5Ohm instead of 1.8, is indeed a large deviation from spec. Does that make it a bad atty? No, just an atty that is not LR and can be used at 5V. OTOH Isaac definitely want's to know.
I have to agree, 2.5 or 2.7 is something Isaac should be aware of and rectify. Like you say, doesn't mean they're bad, just not LR - though not everyone has a MM, or vapes at HV. Personally I haven't seen any so far off the mark, either I've been lucky 20 times or folks are reading their meters wrong..
These are my favorite atties for now, they have the fastest (though admittedly roughest) break in, and last me about 3-4 weeks with zero cleaning/maintenance. I pretty much leave it on my Reo til it dies or performance drops to unacceptable levels, then toss it.
