"Fine product for a fine price. REX for FS2004 may potentially change your flightsimming experience forever. As one who has been continually tweaking FS2004 since the early days when it first came out, and trying to get the old classic sim to be as close as possible to a real-life flight experience, REX certainly came as a welcoming surprise and have taken my FS2004 to new levels. This package comes bundled with loads of textures that the user can customize to his or her heart's desire. It comes with new sky colors, water textures and waves, airport environments such as taxiways and runways, runway lights and strobe lights, and perhaps most dazzling of all, high-definition clouds. In addition to textures, this package also comes bundled with its own weather engine and flight planner. Furthermore, the developers are still improving this product, so there should be more to come in the future. So, if you are like me who have stuck with FS2004 after all these years, I would highly recommend this product for enthusiasts who are interested in improving the visual quality of their sim. Being once a pilot who have flown in the skies in real life, I would say that this product definitely deserves its title of "real environment," for it certainly brings back the breathtaking feel of the environment several thousands of feet in the air." - Andy Yiu

"This has to be the best addon our there for clouds, water, taxiway and runway textures! Very user-friendly.." - Tristan Ridge

"Like everyone else has said, just stop thinking of getting this and get it already, they are still supporting it, and it really transforms FS9 into FSX almost, amazing attention to detail, I wish all payware addons were like this!" - John Godfrey

"Fantastic product! One of the best flight simulator addons out there, Adds a whole new dimension to FS2004 and the realism improves alot! I truly reccomend this product to anybody! Overall 5/5." - Thomas Emms

"Firstly I want to say I do not normally write reviews about anything,because I am a cranky git....But having just installed REX into my Flight Sim I am really really happy and smiling broadly...It is like having a new sim,after the disappointment of not being able to run FSX (due to my computer specs) REX makes up for this more than enough...Buy it! it transforms a dull sim into a "As Real As It Gets" for sure..." - John Colohan
