I like that you can create subdomains, which is super easy for us because of their customer service team being very helpful with any questions we have! They will also help set up new nameservers if needed as well (we had to do this once).
Easy setup process when registering domains!! No worries about price changes or anything after initial registration either; they are pretty much straight forward all around in terms pricing/terms so no complaints there from our end :) The best part about domain registry is that it has an easy to use interface, fast support team which helps me in solving my queries very quickly without having any issues with their service or products. I haven't come across anything bad so far as i am associated with them for almost 3 years now! If you want your website secured than go ahead but if its just some personal blog then don’t bother because there are other free options available out here like blogger etc.,.
