2 little cons-
The package arrived with many of the cars not secured into the foam packaging, but none were broken and easy to reapply to the packing.
The o-rings on the mouth piece is just a few thou too big and can get pinched between the globe body and the mouth piece if it's not pushed in actively.
Overview:
resistance ranged from 1.35-1.7 ohms. Tested a random sample of 10 and found none to be DOA. The center post is substantially wider than a standard cartridge and this seems to reduce the tendency to clog when using thicker oils. The filling opening is much larger and this may be my favorite feature- This will easily accommodate a 10 gauge blunt needle. 1.50ml leaves some air in the cartridge, and the o-ring generally makes it so the globe can't be filled to the brim anyway.
I'll likely be ordering this product again.
