Despite their automated 90+ performance and the underlying Google cloud architecture. For me, this level of performance came at a huge sacrifice with regards to styling of my website. I thought this may improve with their 'Cloudflare Enterprise' (it isn't really) but not to the levels that I had previously obtained on a Shared hosting server with LiteSpeed. Their support is responsive, the interface of the platform is clean and great for clients but the performance issues let me down so I had to move my sites off their platform.
I'm also not particularly happy when companies don't honour the terms of their lifetime deals for their early adopters, but that seems to be happening a lot these days.
