I see nothing "new and improved" about the Fling minis. 3 hours of light usage (purposely babying it) and the battery is about to go. Grr!
I think that they don't get that the people that love them, don't need them.
I have EgoC, ITaste, Erolls and an 808 at home. A VV Mini Passthrough in my car. I can take an Ego 650/mini, 808 or Eroll out and about... I like the WC minis, but it has to be better than my other options, or more economical.
I love the minis, but I won't spend $3 a day, much less $6 a day on them.
BATTERIES CAN EXPLODE!
Do your homework. Understand The Risks.
If you don't understand it, DON"T DO IT!
