A looong time ago I picked up some Boge cartos from a Chinese supplier for my wife. They measure 2.8Ω on average.
I just ordered some of the 3.2Ω that
madvapes has on sale. Has anyone else gotten these and metered them? Does Boge even make a 2.8Ω carto? Just wondering if these are going to be similar to my older batch in performance...
I just received a box of 3.2 in my last order. I metered two before using them. One was 3.1 and the other was 3.0.
The labeling on the boxes drives me nuts. There is a sticker on most boge carto boxes that says something like "510 D regular" or "510 D SR" or "510 D LR". --> SR = Standard resistance (which I would think would be 2.5 ohms), but with boge, apparently it means "something around 3.2 ohms". "Regular", I would think should also mean standard resistance, but apparently with boge it means "something around 3.0 ohms". The LR stuff is the same way for some stickers but not for others. I get some 1.8 ohm boge from another vendor and the sticker actually says 1.8 ohms on it (most of the time), and most of the 2.0 ohm boxes have a sticker that says "LR 2.0 ohms", but sometimes I get one that just says "510 D LR" with no indication of ohms. Same for the 1.8 ohm stickers - occasionally it just says "510 D LR".
On top of that, sometimes I see strange ohm ratings advertized. Bombdrops Vapor carries a boge 2.9 ohm (probably the 2.8 you are looking for), and only two places I know of carry the 1.8 ohm boge I like for my bottom feeders.
Sorry for the rant, but maybe that will help you identify which ones you are looking for in the future... or maybe they'll change the stickers again and make me more frustrated with their labeling.
