I love their speed to respond when you have questions or need help with something! They are very flexible in what they do best for us (we use them as our site's analytics tool). The price is higher than other similar services out there but worth every penny so far we've seen no complaints about it from clients yet either!! Their support team has been fantastic too - always quick at responding back and helping where needed most :) We're using whizzlurls tracking tools because of how useful that information can be compared between sites/pages within one web property etc..
