The Silipos Gel Toe-caps have indeed been very comfortable for my wife who has many foot problems. They form a good protective shield against abrasion within footware and are hygenic if washed clean after use. Also they stay put on the toe, all in all a very satisfactory device.
The unit operates just as I expected it too - no problems. Attached to my computer easily and I have loaded my picture files on it. I thought that it was not functioning properly, as on available memory it appeared not to have used any, but it had! 2TB of memory is so huge that I've hardly scratched the surface of it yet, so I am impressed.
