I started out with a clone of the 3.1 KF, then got a lite base, then a full lite plus, and now I own 2 full KF lite+, plus a lot of other things including nano kits, extra long tanks and the sort. And the more I look at the 4, I find my Lite plus has nothing to envy it, except for the juice control. I don't think I'll buy it in the near future, unless of course mine gets damaged beyond repair or lost.
Have you switched? Are you glad you did? or do you beleive it was a waste of money?
