I use it to see how much new extensions affect my load time. Really useful and does what you expect it to.
Loved it
Good to know load time on every page.
Does what it says without fuss. A good tool.
Very useful
Чудовий і простий додаток. Must have для тих хто працює з web
Seems that it could be useful because it mentioned 'sign in to Chrome keep history' (paraphrased)but where is that info? I signed it....can't see where to find this useful information...
简单又好用！
good
Fantastic little add-on to instantly monitor web-page load times. Invaluable to anyone tracking load-times of their own websites in real-time.
