I don't have a favorite best pen set, but for the straight oils and waxes I am really starting to like vaping it with a basic coil in a ceramic bowl.
Are any of the other companies that have similar rigs, do they offer replacement ceramic bowls for 510 or 601 threads?
I really like the one I am using, but it is a bit expensive. I had one that just died. Luckily I had a spare. Perfect timing too since I am doing a strain selection based upon the quality of QWISO each produces.
I just took a couple of hits off of the fresh one today. 4 different strains, all of them are great. They are not ready yet, I just began the winterizing process. I did sample them pre-hand though!
I am using a mechanical vape, 3.7V magneto with a 510 to 601 adapter to use the 3.7V Persei KISS Cart.
Here is what it looks like new.

After I am finished testing my strains I will load this up to the top!
The first KISS cart lasted through somewhere between 7 and 10 grams of oil. They cost $20. I cleaned it up and took it apart and it looks like I may be able to rebuild it.

When these are all winterized, the oil will be even cleaner looking. It is going to be dedicated to testing new vaporizing products. Of course I will be using my KISS cart until I find something better for straight oil.
The oil in the pics was all extracted with 99% iso and is being winterized with 96% (192 proof) polish vodka.
Do those globes have a ceramic bowl?
