I have been an ITR user for years. If you ever call you'll probably speak to James. He has put out many variations of the ITR and all were fantastic products. As hard as it is to believe, he took a fantastic product and made it better. The new ITR 2004 is by far the finest product available. The standard size unit which is about 7 inches long has a very smooth retraction. With this unit you can walk 20 feet away. The smoothness of this ITR has to be seen to believe. I give it the thumbs up.
