I don't know about any of that but I can share this bit of news ... My go to online shop for MVE pods now only has all the great and various flavors in nicotine free and saying discontinued. I would assume that now you are only able to purchase pods with Blu flavors. Though I like the flavors, I'm not thrilled. I wouldn't be surprised if they find a way to not allow us to refill ... though on the Blu website it says you can.
I can confirm that the pods can be taken apart from the bottom.
Got the myblu starter kit with 5 pods for $5 plus tax shipped. It's also available for $1 with only 1 pod. The nicotine concentration wasn't well suited for me. They offer 1.2% or 2.4%. I also didn't like the taste. I took a couple puffs and and then dumped the liquid and replaced it with Mr Salt E which I enjoyed much more.
The device works okay. As a smoker who just switched to vaping, I like the ciga-like shape, of course. The draw is similar to the Juul. It is much more consistent than the Juul and the vapor production is better than the Juul also. There is some spit back with the prefilled pods as well as after I refilled them with my own liquid.
Although I was able to refill them, I didn't see it advertised as refillable on the website. Maybe I missed it. The design really isn't ideal for refilling. And the pods are a bit leaky. I only see filled pods on the website. Unless that changes, I probably wouldn't continue to use the device once my pods burn out.
