What does the company do well? Nothing. Sitelio is completely trash. Customer support lacks knowledge, knows nothing, very helpful. I did not choose Sitelio in the first place but was forcefully transferred from Ideahost. Sitelio is even worse to the fact that it does not let you edit dns settings and the website building is buggy. My website randomly has these white lines appearing out of nowhere that do not show in preview but in the published site.
What does the company not do well? Everything. The company is trash and the hosting service is horrible. Customer support tells me that my website has unlimited bandwidth since I have the most expensive plan, but my small website takes 20 seconds to load. Sometimes the images won't even load. The website builder is so buggy that I keep losing my works. Using this service you can not just get a ssl certificate for your website, but just this hosting service, you can't even edit dns or CHAM records. Completely a waste of time contacting customer support, no knowledge at all and one time a guy even disconnect on me.
What about the company do you wish you had known before purchasing? I did not choose Sitelio. I was originally using IdeaHost but was transferred to Sitelio and I had no other choice but to use it. Very disappointed at the service, I'm saving up to switch to Wix.
