I have been using this since 2015 when it was free, now that is expensive. You can get what you need for cheap in free services like CloudFlare or Google. We are using it as our domain registrar and it performs fine and fast. Not much to say here if anything its just work great so far! Free options are good to test your business plan first before going proprietary solutions like usa, we've learned alot of things from the free versions! It also help us keep costs down which most customers love too. It is very easy to use and it is compatible with most of the software including windows.It provides me with all i need as far as DNS hosting is concern.it has an error sometimes which takes time to fix.But everything works fine if fixed properly.I also like that they have a one year trial period so you can try them out first and see if this will work for your needs. I am solving my dns related issues like resolving dns cache problems,dns slow speed issue etc.
