Did not get this for what it's intended, I want it for another unusual job, will be fitting it soon, making a water tight seal around a pole were it fits to a roof, had it suggested by someone else, there is a great deal of difficulty getting a replacement for the one that has gone done, this was suggested as a excellent replacement. So I am going to give it a go.
No Idea how well these perform as C.V. gaiters. However, they make excellent snoots for INON Z- and D-Series underwater strobes, and due to their flexibility will probably many other strobes too.
