Hi,
I just wanted to share my recent experience with Siteground. I was with another host for 5 years and while I loved their customer service, their servers were not great and they tended to overload them frequently.
Whenever I would check in or complain they would fix any issue or even move me to a better server but speeds were slow.
I decided to start the research anyone does before switching hosting providers and landed on siteground.
We just opened the account this week and I opted for the "free site transfer" service. I have to say I am very happy! I gave them the cpanel info from my existing host and within a couple hours received a notification that all data was transferred. All I had to do was update my DNS for my domains and it was all done.
I have switched hosting companies before with less domains and it was never this smooth of a process. So If you are looking, I highly recommend siteground.
Hope this helps those looking for a better quality host.
