Do the Apex disposable pens come pre-filled?

I really love the Rubi

Yes, more reliable than Rubi but less vapor production. Both are excellent, not sure the Rubi pods are worth the premium vs 510 carts

I would suggest the Rubi too but yes they are prefilled

Yes and I will say I was very pleased with the quality of them.

Yep the Apex are pre filled, disposable,and garenteed for the full use.

Yes
