I just received my minifit max today. It is identical to the original minifit, but with almost twice the battery life at 650 mah. I really like it even though its bigger, but having the extra battery life is worth it. The smaller minifit already had very impressive battery life for how small it is. The minifits are still my all day vapes, just wanted to let it be known that these are available although I had to wait for shipping from China. Going to try and find anyone in the USA selling them and get a couple extras.
