I bought this product and used it for a short while. I sent it back. As others noted, it is too short to take the place of standard plastic dilators. II bought it because it sounded exactly like what I wanted - something that could be systematically expanded while it's inside you. It also has a digital readout that tells you the diameter, so you know exactly how you are doing.
The downside, aside from being too short, was that is expands through the use of four metal bands, so it has a shape roughly like a bell pepper when expanded. That means it can hurt when you twist it.
It comes in a very nice plastic container that doubles as a charging station. I think it would have been great for travel. I am tired of getting pulled aside by TSA inspectors who want to know what my dilators are. (I finally started taking my dilators out of my luggage and putting them through he scanners separately.)
