I like that it is easy to use with no technical knowledge required - you can just click "Add" or select an existing website from their database of thousands! It's also great because they are always improving things so there isn't really anything we don;t love about our experience using them over last year (and years before).
We have been able solve many problems related directly back-end issues which would otherwise cause downtime during peak times when people come in numbers at once such as concerts/fairs etc.. The only issue i'd say could be improved upon slightly was how long does this take? Sometimes if your site has already had some content published then sometimes its not updated straight away but thats easily solved by adding additional servers / increasing capacity online thoughout out day time hours rather quickly afterwards too :) Would recommend 100% definitely!! They've saved us loads off stress knowing everything will run smoothly without any down periods due delays caused other wise through lack availability within infrastructure.
