I used this Component over the other 4 leading components I consider for my Rental site. Koparent is the best in terms of ease of use, functionalities, and awesome support. Oh... the price is very reasonable, I would not care paying double for what I got and the support they are giving me. I am a Joomla user (the first CMS I learned) for about 3 years. I highly recommend Koparent. Thank you for this great tool.
