Real time saver and great Component Builder tool ! I have been developing with J-Cook Pro Component Builder for several months now and can say with all honesty that this product/service is second to none. The product is feature rich and is being improved and added to all the time. Do yourself a favor, if you need to build a Joomla! Component then you can do no wrong in trying the product. You will save on time and effort while being able to deliver your project on time. J-Cook pro does the hard work for you, you then have the freedom to fully customise the end result for your own needs.
One word: Awesome.
