I can only say positive things about Cloudflare: it is fast, very easy to set up, never gives problems, it helps you even when the site temporarily goes out of service, you do not need assistance because you already know that you will not have big problems. All this is free (unless you need some specific options that you will pay dearly)

I would have only two details to say:
When you add the site in Cloudflare, he goes to scan all the possible subdomains and, if he receives the famous answer 200 (so that the page, and consequently the subdomain, exists) he will automatically add it. What does it mean? Some hosting always give a positive answer, even if the subdomain doesn't exist. In this case CF will create hundreds of non-existent DNS records to be deleted one by one (because it does not provide for bulk deletion)
Second thing is that unfortunately it does not plan to have dedicated IPs, even in the high paying plans.

Cloudflare has a lot of features that can help optimize any website speed and performance, it also offers free security tools to protect website from popular cyber attacks.Some of the features I use frequently on cloudflare includes, the free SSL certificate to encrypt data from the host to cloudflare network and to the browser of the user.The content delivery network feature, web caching, Speed tools and protection services against hackers. Above all, most of these features on cloudflare are free to use, no charges at all, and they are very easy to setup. The extra features that are not free are also very affordable.

I have no complains since I have been using their service. It is really a great tool.
