I really enjoy this tool as it always gives me an overview of what’s wrong with my website which is super helpful! It also helps to get suggestions for improvements or things we can add ourselves later (like more images). The way each screen displays everything in front/at once was quite overwhelming so maybe try doing some research first about all options that are out there? But overall its pretty easy-to use - very detailed reports show you exactly where problems lie without wasting tons off time trying different variations yourself.- There's nothing bad i've come across either yet since using their product daily over several months now.. just do any changes if they make sense but don't be too drastic at points otherwise it might break something down below somewhere else etc! You'll eventually find new features coming up every week from them usually adding useful functionality while keeping existing stuff working well together somehow still too hard sometimes though haha I like that it is a free service, and that it is customizable. I'm able to use it with my personal site, with a client, and with a company. The biggest benefit is having the site render fast. I have seen a difference in speed, and the site is more responsive. I also like that I can use it with different browsers. I've noticed a difference in speed between IE and other browsers. I've also noticed that it is faster on mobile devices.
