I was quite impressed by their online platform. However their service has started to slow down since i last used it in 2017. Their customer support is always quick to respond but sometimes a bit unhelpful. Also the online platform is still being updated and added to.
Overall they do an excellent job at keeping things clean from end-user perspective (no unnecessary clutter). They also allow you to easily share your work publicly which is good as long as there isn't too much sensitive information
