New to concentrates, what is this?

[LesPlenty]

I have the banger, 710 coil, auber setup and the times I've used it I can't get a great experience with the smaller amounts I use. That same amount gives me a good hit in my erig bucket.

I tend to agree, I have 3 different-sized bangers and inserts but I need more in them to get the dense cloud I want compared to the amount on my DNail SiC Halo and it is so much easier to maintain.

I like dab pens for their stealthiness, never as good as my Halo but look at the size difference.
I will agree with @Bologna that consuming concentrate in a herb vape is a waste...just use the herb, that is what it was designed for!

If I draw on it too long or let the coil run dry then you can get the hot, coily, shitty taste.

Very wise words, the Terp pen is a handy device for a sneaky puff with pretty good taste if used right ...just don't run it dry or try to bulldoze a track through your rosin etc!
