I have a Yosen V1 Zero and the Infinite Zero (Yosen V2 repackaged). Both read ohms slightly lower than what they are. My 1.2-1.3 builds always read 1.1-1.2 on the Zeros. No biggie since the power is easily adjustable. The 510 on my V1 is fine but I don't like the extra punch from the chip. The V2 power delivery is a little flat but it suits my style of vaping better.
Will probably trade or sell the V1 for cheap when I get around to it.
By the way, does anybody know someone that will take gear or cash to swap a dna board into the Zero for me. I don't have the time, skill, or resources to do it myself.
I think I was the only one who liked the punchy chip of the V1, I still use it and never have dry or burnt hits with it. The V2 chip is totally flat to me and I don't use it at all for that reason. It otherwise works fine, does not have any issues, I just don't get what I want from the vape. Both do read .1-.2 below other devices as you said.
I posted in another thread that the SXK Vapor Flask V2 (same as Yosen and Infinite rebranded) this chip seems to be right in the middle of the V1 and V2 chips. Not punchy, not flat, so I do like the vape I get with it. The chip still reads .1-.2 below on resistance like the others ... some things never change.
For your chip transplant, maybe try making a classified listing for Trade, with the trade being chip transplant services?? Not sure if that would be prohibited or not, but I am sure you can pm Classwife and ask.
