I love the ease of use the product offers me. The notifications are very effective and they are super fast! Also it's free to try the software and all information is clearly defined in the documentation (which is really good!). They have been adding new features every week which makes using this product very nice. There isn't anything i dislike about this product as of now. It works great and we haven't experienced any issues with their software yet. Try it out and you will not be disappointed! We were able to provide our customers with more personalized experiences and deliver timely messages to them.
