Above 50,000 users and 3 reviews?
Totally fake number of users.
Addon overrides search engine and don't even look at the Privacy Policy.

This seems to be a self-installing piece of the Chinese effort to take over the World Wide web. I am reflexively suspicious of any sort of Custom Web Search which is only customizable by the developer. If you are reading this review, my expectation that all reviews are automatically deleted which are not in Chinese, or maybe not 5-star will have been proved wrong.
