I've been a Retspro customer for around 4 years I believe. As a developer myself, I was looking for a solution that will allow me to modify the code and make changes as needed if I wanted to. The WP-Realty plugin fits the bill quite nicely.
For the money, the plugin is a great value. The team at Retspro has always been willing to help and quick to answer any questions that I may have. The level of support is personal and you get the idea that they really care about your success.
You can't go wrong with Retspro!
