RECEIVED THE REVISED LONGER / MORE NARROW DIAMETER MODEL. A COMPLETE WORK OF ART AND IS A SECOND SKIN WITH NO CHANCES OF CHEATING. ( I UNDERSTAND WHY YOU GENERALLY SELL THE STANDARD ENLARGED DIAMETER FOR COMFORT, FIT AND EASE OF PUTTING ON). THE LONGER / MORE NARROW DIAMETER VERSION TOOK ABOUT 30 EXTRA NERVOUS MINUTES TO PUT ON BUT WELL WORH THE EFFORT. THE BEST DEVICE ON THE MARKET.
