@aleksandrx note that Asset CleanUp is not a one-click solution and it just takes a bit of time to set it up, but the results are well worth it.
Your feedback is really short and suggests that perhaps you haven’t invested enough time to check it out?!
Some of the features that were locked weeks ago (including combine & minify JS files which are found on other free plugins) were released to the lite version. The freemium model is there for a purpose. Most of the free quality plugins out there won’t be where they are without having a Pro version to support them.
The main purpose of Asset CleanUp is to reduce bloating caused by CSS / JS files. Combined with a page caching plugin, this will guarantee an improvement of the page speed score, as the plugin suggests.
Could you explain in more details what you mean by “All functions are disabled.”? What particular feature you couldn’t you use that you found essential for the page speed score?
I wish you would give the plugin another go whenever you have the chance and perhaps you’ll change your mind about the “bribed” reviews statement. You saying that, is just an emotional reaction to whatever bad experience you had in the short time you used Asset CleanUp. I suggest you open a support thread on the forum if there are functionality issues.
Best wishes!
