I have a SR10 and was using it on a 2 week adventure i did notice a couple of things,
The rubber cover for the PPT port disappeared on about the 3rd day. i used with the ppt button attached but it can used without it so a more durable flap is needed.
Also taking the unit off each night for security, i noticed the rubber straps were loosing some of their "tightness".
It would be nice to know that we could purchase the rubber straps as a spare part if they were to fail.
