I'm coming up on 4 weeks of vaping and I think I should buy some more atomizers. There are tons and tons out there and I'm just not sure. I always hear about boge cartomizers. Are their 2.5 ohm attys any good? is 2.5 ohm standard or is it like in between?

I'll be using eGo batts if that makes any difference. I dont much care for the LR atty I have, but it could just be the few juices I have dont go well with LR (and its likely not very broken in and Im just used to my well seasoned stock attys). I appreciate your input!
1.5 ohms is the lowest impedance for what is regarded as LR atty's.
I hope that your LR atty was cleared of any and all primer fluid. (its nasty)
Some juices will taste different when vaped at higher voltage in a 5v or 6v mod.
The same is true to a certain extent that some juices when vaped with with a LR atty will taste different, sometimes stronger.
Most people use LR attys to attempt to simulate high volt vaping.
Most of the standard batteries are rated at 3v - 4v.
When a low resistance atty is used with these standard voltage batteries, you will get more vapor, more throat hit and you feel like you are using a 5-6 volt mod.
The down side is that they do not work on most passhroughs very well which are usually close to
5v. LR atty's should not be used with most 5 and 6 volt mods as the coil usually burn out quickly.
