Well, it arrived. I have no juice, even though I ordered the eroll and Halo juice within 15 minutes of each other, so I can't use it. Things seemed somewhat charged out of the box.
Con #1: I wish the cart/mouthpiece was softer. I guess I am spoiled by the Flings. Love their tips.
Con #2: Charger did not come with cellophane film, and had small scratches out of the box.
I hope I get to the pros when I use it.
