I was in the last lokka group buy, installed it myself along with a diff drop kit, off road they are amazing it doesnt feel out of the norm and it just let me 'goannawear'
the only down side ive noticed is that if you use it on dry pavement it pulls the car a really good amount, although as stated in other posts prior to me purchasing, the 4wd isn't meant to really be used on dry pavement even before the lokka, the other thing I have noticed at least while driving in Colorado roads this snowy winter, is that when i'm letting my foot off the gas i can actually feel the lokka disengage as its suppose to similar to if i was turning and releasing the throttle but when you give it gas again and it re-engages it gives a little tug to the side,
Overall i'm really happy with it, I got it for off road and when it comes to that it does exactly what they say it does, its a great bang for the buck, it doesnt take much of a rotation to engage or disengage when going from 2wd to 4wd.
