I like that it has a lot of different options, some of which are great. It's easy to use and you can create pretty cool looking domains. The price seems high at first glance but you really don't pay much for the service as you do with other services. There is not a ton of explanation as to why people are using this tool, but it's useful in its own right. You can easily make your page more mobile friendly by creating short URLs. It just takes a little thinking about how to create those. It's also easy to integrate into social media sites like Instagram and Twitter. There are no downsides as far as I know. If you're interested in trying it out make sure to try the free version. Make sure it works well for what you want to accomplish. I've been able to make my pages look better for mobile users.
