Feedback

    * Hi all, I'm working on a new project, and this is the first time I've ever looked for a JavaScript obfuscator. I was trying to use the Javascript Obfuscator 4.0 trial version on my javascript file and as it appears to find and java script obfuscate all my variable and function names. Also it works very quickly even with big files.

    * Great program! I am a licensed customer and find the software very useful. Javascript Obfuscator greatly compresses size and improves download time and execution speed of the protect javascript files. Obfuscated code is impossible to re-obfuscate and extremely hard or unrealizable to understand.

    * I have tried the evaluation version of your JavaScript obfuscator, everything went fine, it looks really nice. I really like the ability to add a comment header to each compress javascript file. I use this option to include a copyright notice in my commercial script.yuicompressor web server

    * I've been looking for a flexible obfuscator and I downloaded version 4.0 of your product. I walked through the example in the Step by Step and I really like the result. Thank you for a great javascript encrypt tool!
