Rick, I've been running the lr306 on my SD for over a month. They seem to be almost bullet proof except when your button gets locked on and fries the battery. It vaped better than the lr510 and is great with a drip tip. I had to put a 510 adapter on my SD but it doesn't add much length. It is my favorite atty for 3.7v.
