I like that it is very easy to set up an account with them as well how they provide great customer service! They are always there when needed so far no complaints or issues at all from my end but if something goes wrong then support team will help us in resolving our issue right away without any delay which i love about this product because of its reliability factor! Best part for me would be their free website analysis tool called Site Advisor which helps identify things easily by just analyzing few details related to site's performance etc., It gives detailed information regarding different aspects such web server configuration settings along side other factors affecting speed/performance of webpage including compression level used (gzip) among others.
