We have been using ad clear for over 2 years now with no issues at all from them! They are very professional in what they do but not pushy or anything like that - just get it done right. Highly recommend to anyone looking into doing some tracking/analytics stuff!! The only thing I dislike is how complicated things can be compared when you're new so if there's something else out their which makes your life easier then go ahead because this one isn't as user friendly yet (but getting better)! Trying to figure our ways around Google Analytics has really helped us see where we stand before making changes too big-picture level such as website design etcetera).
