Mr.Modzzz a professional. I have use a lot of his modules. Very-very easy to install, looks very good, very necessary and useful additions. I just got this module "Preload", installed it and configured as wanted. It looks awesome! In the pack 30 different preloaders, i choose one, background like site backbround, and you can look at it (i don't advertize, just wanna show the effect - https://www.sovremennoepravo.ru/). It awesome script, users love it, it look modern!
And if you got a see more problem - just tell him about it, Modzzz always will fix the bug
Very friendly and good guy - that's my opinion. I used Modzzz modules, I do, and I will.
Thanks man for you job!
