The ease of use is incredible! It's been so easy to integrate into our platform that I actually don't even think about it anymore. Their customer support has also always worked with me super quickly when we had questions or issues. We're still using them at this moment but are considering moving away from their services once they have more time under there belt as well since many other options do offer similar solutions - including free ones if need be!). There haven't really any downsides yet which isn't bad because things usually take awhile before you find something not working properly out here :) Still early days though where anything could come up down the road just stay abreast, talk directly wih the retargeterkits staff & keep us informed. Our traffic acquisition rates through reTAGgetKIT was amazing within 2 months or I love how easy it is to use! It's very simple & intuitive which makes my job easier since i'm not used with this type of software before - but so far everything has been great!! The support staff are also really nice as well when you need help or have questions about their product they will answer them right away :) Great platform that helps me maximize conversions from Facebook ads even more than what we were able previously doing manually using other platforms such as AdRoller.
